LVC Day 4

Even though I hadn’t had too much to drink the previous night, the lateness, as well as it being the 3rd or 4th night on the trot made it all the more painful waking up. As I was sitting in bed chatting to Daniel, waiting for Jennie to finish in the shower, I got a call from Joe. Morning calls are usually a fixture, but the schedule had been a little tight this week, so I jumped at the chance to get as much chat in as I could.

Another day, another muffin. I just wanted bacon. Just once. But a muffin and a bucket of coffee later, and I felt only slightly more human.The agenda for the talks today were predominantly data analysis focussed – computing budget, burst search results,  and stochastic search updates. I always think that the stochastic updates are neat – their group, instead of looking for individual events or sources, are more concerned with detecting an ensemble of unresolved results. As such, they have extremely different results to present, from some relatively off-the-wall methods when compared to other search groups.

Alas, the week was starting to take its toll (and yes, I did just use the word “alas”), and after a talk or two, I decided that what I really needed was some peace and quiet. Sitting in the back of the dark room just wasn’t secluded enough. Unfortunately, though,  housekeeping were in the hotel room, so I came back down and felt sorry for myself for the next hour, until the morning break.

The day carried on in much the same, but food at lunch perked me up. Look, I don’t think that muffins and pastries are in any way appropriate for a breakfast. Not even once. The addition of melons and strawberries was no consolation either.

Lunch on Thursday was the LAAC lunch – some of the LAAC guest alumni stuck around to talk to current LIGO students, and this was our chance to rub elbows. I sat on a table with Tobin, an ex-LIGO now Google employee in San Francisco. The food was mexican – but I couldn’t tell you what. I honestly can’t tell the difference between the styles of wrap. The talk at the table was interesting – not just on experiences post-LIGO, but also about what it’s like to work at different institutes, the benefits of working in various working groups, and the like.

After lunch, I was back in the hall for the stochastic talks. Always interesting, and always eye opening. Their aims, to detect the gravitational wave background, is like trying to characterise the murmur of conversation at a bar, but not to resolve any individual words. It strikes as particularly challenging as their search isn’t for a given waveform, or for loud events, but is very dependant on cosmological models. It’s a unique challenge within the LVC, and utterly fascinating.

After the final plenary of the day, we were kicked out so that the hotel staff could set up for the conference dinner. Vinny, Paul, Daniel, myself and a few others decided to head to Caltech to have a nose around. On the way to meet the others at reception, I was stopped by Susan. I recognised her from the dance floor on Tuesday night. She said that she was here with a film crew, and were filming the event for a post-discover era documentary. She told me that she likes to interview people with more energy, and that she was impressed by what she had seen on the dance floor. Susan asked if I would be happy to be interviewed for the documentary, and of course, I jumped at the chance. It meant that I had to reduce the amount of time I had at Caltech, but that was a trade I was willing to make. I was to meet her when I got back later.

The walk to Caltech took about 20 minutes, and when we got there, none of us knew where we were going, or how to get into any buildings, let alone which ones would be best.

We milled around the courtyards for a while, but before long, I had to head back to meet with Susan. Before I went in front of the camera, whilst they were talking to Nutsinee, she asked me some questions about my research, about what I felt about the kind of events that go on,  and about what its like working in the collaboration. Then, it was my time. I sat on a stool, I was micced up, and Susan led me into the interview gently. It was a nice experience – though I became very aware, as I was speaking into the camera, that what I said now might be made public, so I had to pick my words a bit more carefully than I might otherwise.

And then it was done. in ten or fifteen minutes of the same questions all over again, I was excused, un-micced, and I was on my way.

The conference dinner that evening in the ballroom was on the face of it a formal affair. Large round white tables, white tablecloths, a 2 forks, 3 glasses, and a waiting service. I had chosen to sit on a table with some familiar faces, and ended up sitting next to Max Isi – a Caltech student who I had seen about, and who worked within the CW group, but never had a reason to talk to. He made for good dinner company. The food of the evening was nice, a salad to start, chicken (was my choice) for main course, and a nice fruit tart for dessert.

After the food, it was time for the talks. Always expected at this kind of event, and usually delivered by Gaby, plus someone from the hosting institute, it was a little different this time. These talks were presented as a retrospective of how LIGO, Virgo and GEO came to be. The first speaker, Rai, spoke about how he came to the idea of an interferometer and about how it was to work on the prototypes at Caltech. What stuck with me was how different the landscape of the field was then. It seemed like there were just a fistful of people working in a lab. I guess with the tinted glasses of retrospection, all things tend toward fondness.

The second speaker, whose name I did not catch, told a parallel story of how the field developed in Germany, right from the early Webber bar detectors up to the start of the interferometric era with prototypes towards GEO. Third, Jim Hough spoke about how Ron Dreaver drove the field in Glasgow, about the 10m prototype, about how the British-German coalition came together to form GEO, and about the development of the 4-stage seismic isolation. The whole thing felt like looking back through a family tree, and exploring what led us, as LIGO, as Virgo, and as individual scientists, to work in the landscape that exists today.

After the speakers had done their part, the dinner guests broke out, some to the bar, some to their rooms, and some out into town. I stayed at the hotel bar for a time. The drinks had been discounted for this last night of the conference, which made a nnice change. As I was outside chatting in the courtyard, it seemed as though most of the conference was heading to the same bar – T Boyle’s – for some St. Patrick’s day celebration.

Foolishly, I joined them.


The atmosphere there was great. LIGO made up about half, if not more, of the patrons there that night. The bar had a cover band in. They weren’t particularly good, nor were they particularly bad, but they were having a good time, and it was reflected in what they played. The whole LVC crowd occupied the upstairs balcony area, more than thirty of us, easily.

As the night wore on, I found myself hanging outside with some others, gasping for air. There, I managed to meet what might be the only other LVC scientist from Somerset! He, Tom, was from Cheddar, and it was nice chatting to hiGuinessm. Once the band had finished playing, it was only another half hour before the bar kicked everyone out for the night. At that point, the group split into three. One party headed back to the hotel, another went to somebody’s apartment to carry on the fun, and a third party split off in search of alcohol to take to the apartment.

I found myself in that third party, but after ten minutes of walking back and forth and getting exactly nowhere, I figured that I should really go back to the hotel and split off to walk back alone.

You can see the aproximate locations on the map (you might have to pan down to California)

When I got to the hotel, I found a subset of that first returning party in the lobby. Having come back already, they had changed their mind and decided that they really wanted to stay  out. I have no will power, and am very susceptible to peer pressure (at least, that’s what I tell myself to make me feel better about bad decisions), so I ended up walking the 8 or so blocks with the others to the apartment.

When we got there, before we could even ring the apartment bell, bodies came pouring out. Duncan frustratedly said that they had had a noise complaint (it was very late on Thursday night) and the guests had to leave. That was it for me. It was definitely a bad idea to stay out any longer, so I turned tail and led some people back to the hotel.

By this point, I was pretty proficient at slipping back into the hotel room.

LVC Day 3

Another day, another muffin. Another night of not as much sleep as I ought to have had. Another cup of coffee.

Wednesday was the first day of the plenary sessions, these are the broad reaching talks which are aimed at all of the LVC, not just specialised talks for those who work closely to the subject. Today was the parallel session for the LAAC (LIGO Academic Affairs Council), where I aimed my attention first.

I was quite dismayed to see that the LAAC didn’t do in their session as others had done in theirs. Instead of discussing academic affairs, whatever that might entail, the LAAC session was run as a tutorial for a discreet set of topics which are very relevant to some, and less so for others. After the tutorials, the LAAC had gathered some LIGO alumni who had since moved on to work in big industries, which seemed like a much more relevant topic. Honestly, though I wasn’t pleased with the content of the LAAC session, I wouldn’t know how to run one. It couldn’t be on university policies, or academic writing tutorials, as the collaboration is far to big to cover all bases. I just didn’t like that session.

At my first opportunity, I left for the other plenary talks, which were running in parallel in the largest room, where last night there was  dance floor. At every LVC meeting, the first few talks are “The State Of X” talks: the state of the LVC, the state of the LIGO Labs, the state of Virgo, the state of LIGO India, the state of KAGRA. Last year, at my first LVC, the talks were interesting, but thick, and hard to get through, as a first introduction to each detector. At this, my second LVC, the talks seemed like a jovial “Hey, how’s it going” exchange. Now that I’m acquainted with each machine (even slightly), suddenly, it’s a lot easier to be interested.

The general feeling was one of progress. In fact, KAGRA, the Japanese detector in the Kamioka mines, had managed to lock its Michaelson interferometer earlier that very day. LIGO India had achieved “in principle” funding, and was generally looking up, Virgo was well into its construction, but was teething, and LIGO was between observing runs, commissioning, but still reeling over GW150914.

After a brief lunch, I took a walk to the tea shop with Daniel. We discussed this and that, ideas about LIGO India and Virgo, and had some very nice iced tea to cool us down. The afternoon plenaries were more general overview type talks. Interesting, and nice to see, but not really much to comment on.

Later that afternoon, once about fifty people were bussed over to visit SpaceX for a tour (what, no I’m not jealous), we had the poster session. First was the flurry of sparkling presentations. Each a one minute snapshot of a poster as an advertisement. I tried to convince Vinny and Jennie to give a talk, even though they hadn’t prepared a slide. It was a “They’ll only do it if you do” kind of persuasion. Sorry guys! We moved into the poster room, and all milled around the posters.

This is the first conference for which I didn’t have to create a poster, it was nice to be able to look around. I had an eye out for posters on CWs and CW searches, but I didn’t see a single one! Perhaps I should make one next time, just so we get a showing.  I asked a few people whose poster wasn’t about GW150914 about their poster (there had been a lot of information about GW150914 in the months leading the conference). Some of the interferometry ones were quite interesting, but they were mostly from Glasgow, so I’m biased!

That evening, I had plans, meeting up with a tenuously traced family of a friend of my family, who lives in LA, and was described as something of a science nut. I had planned to take him out to a house party at Jenne, Jeff at Nutsinee’s Airbnb. But before that, I had to cram in some food. I met with Daniel and Sudarshan in the hotel lobby, and we walked down Colorado Avenue to see what was around.

We settled on a noodle place, where I had veggie ramen and Thai iced tea (which, by the way, is tasty). It was nice meeting Sudarshan – I had heard his name banded around LHO, as he was here for about 18 months before heading back to Eugene, Oregon. I never got to meet him before this week. Names and faces, right?

Having eaten, I waited in the hotel for Dave to show up. He was coming to meet me at the hotel. He arrived about 8 o’clock. On the way to the house, we chatted a little. He described his job – an editor for some mindless reality tv shows, the example he gave was Keeping Up with the Kardashians. But what he really wants to do is to be a writer. He has some children’s books on youtuve as audiobooks.

We  arrived to the house party, it was a pretty chilled affair, beers, sofas, music through laptop speakers, and a whole bunch of LIGO people. In one corner of the room, ten minutes after we arrived, Jamie started playing his LIGO boardgame with a few others. The game lasted about an hour.

We keep half an eye on the game, whilst Cao, Cody and I picked Dave’s brains about the media industry, about living in L.A., and he asked us a bunch of questions about gravity, quantum entanglement, and some other cool weird physics. After a beer or two, he headed off just after midnight. I stayed for another half hour and chatted to those who were there.

At the time of night when others were struggling to make plans to split an Uber, or whether to get a Lyft instead, Cao and I decided that it would not be beneficial for anybody if we stayed. We walked the mile or so home, and I snuck into the hotel room when we got back.

LVC Day 2

Another day, another muffin.

Though this time breakfast ofr me also included various melons. After a coffee, a mingle with some GWers, and a mouthful of sugar, it was off to the San Diego room for the second, and final day of the CW f2f meetings.

Today, many of the talks were focussed on sharing results from the old science runs S5 and S6 from iLIGO, as well as a few quick glances at preliminary stuff from O1. Not just the results, though, but updates in various pipelines. There was a little bit of musical chairs and some talks weren’t going to be presented, so others were brought forward.

At lunch, Jenne had promised to introduce me to her friend Greg, a researcher at Walla Walla (A town not too far from the Tri-Cities) who knew all of the good gay bars near Pasadena. His favourite was a country themed bar where they have square dancing lessons. It sounds fun, but not really my thing, and I didn’t bring the right shoes for all of that. We met over salad and pasta, though the lunch hall was busy by the time we got there. I managed to not sit by him to eat, instead sitting by Ryan – the network specialist at Hanford. Ryan and I spoke about this and that, having not really exchanged much more than a “hello” before now. So that was nice. Following food, a handful of people, myself included walked around the neighbourhood, to catch the sun whilst it was out.

After lunch, I headed back into the f2f talks to catch Avi’s talk. He had been doing some theoretical work on Ekman pumping and GW emission within a neutron star, modelling the length of this kind of glitch. I presented the paper upon which his work was based at journal club a few weeks back, but it was nice to see it again, and he furthered the work to predict the length scale of tCW emissions in various fluid models. It was a really interesting presentation.

After the next session, in the afternoon break, a few of us CWers met about tCWs. There are a core group of 8 or 9 people who work towards this, mostly distributed in Glasgow (myself, Matt and Graham) and AEI Hanover (Avi, MAP, Reinhard, David etc), all working on this common goal (all be it in a handful of parallel ways). It was twenty minutes to discuss ideas, implementation, and prospects for development and incorporation into pipelines.

After the break/meeting, I had decided that I would sit in with the EPO (education and public outreach) meeting for a moment, before Grant’s talk back at CW. Martin, Glasgow’s head of school for P&A was there, so before the meeting got started, I chatted to him about some ideas around the Glasgow Science Festival week in June, about some scrapbook  of highlights from this blog, a short video log in various places about LIGO, maybe a time lapse of the the Y-arm from the roof over a day to get the sunset and the stars moving around.

When the meeting got started later than I expected, there was talk about a board game developed called “Observe”. It’s a LIGO game, where players, each with their own model IFO, must prioritise commissioning, research or observation in order to first detect gravitational waves! Let me find a link – no luck, it wasn’t in the slides. I’ll come back when I find it.

[EDIT: The link to the game is here: It’s still somewhat beta, but it’s VERY playable, and quite fun]

Before we could get to the social media part, where I might have brought up this blog, I headed back to the CW room to catch the last two or three f2f talks for this meeting. Sfter which, it was time for the LAAC’s Detection Party.

We had each been given one free drink token for this night, though it couldn’t be used on the LIGO cocktails that were made special for the occasion. After an hour of wine and nibbles on trays, we were called into one of the larger rooms rooms for the obligatory speech from Gaby. (Gaby being the LVC’s spokesperson, who must spend ~50% of her time writing one speech or another announcement).

After some well picked words, a few rounds of applause, it was time for our world record attempt – the worlds biggest chirp. Chirping was a social media campaign started about the time of the detection, where chirpers would sing the sound of a BBH inspiral (Well, it’s really a BNS as they’re generally higher pitched and longer). We had a few hundred people doing it all at once. A ceremonial slice of GW150914 cake was cut, and it was go time for the party.

In one corner of the largest room, the hotel had set up a small dance floor, and had some big ol’ speakers hooked up to an iPod. After a first dance from David Reitze and Gaby, everybody piled in and had a good time to some cheesy classics for a few hours. Dancing in Cali gets warm. By 10 though, the hotel said it was time to move along. My mind went straight to karaoke. A quick google showed that a place nearby, Barney’s Beanery, was the only karaoke bar for miles.

A handful of us, maybe 10 or 15 headed that was, but when we got there, the place was busy, and karaoke was off the table. It was, after all, a Tuesday night. We decided that it would perhaps be better to go somewhere quieter with a more chilled atmosphere. In the Beanery, we ran into some faces from the LVC – Christian and Melody, who recommended a spot around the corner, King’s Row, saying that they’d meet us there.

And that they did. It was a nice bar. We each had a go at buying each other drinks, we chatted about this and that, order 2 plates of chips (fries). Jennie and I, both from Glasgow, were talking to Melody a lot about Margot, mostly old stories from her days at Caltech. Melody and Margot were once, it seems, best buds. By 12.30am it was well past time to head back to the hotel. Sneaking in, trying not to wake the other two would get easier throughout the week.

Einstein Was Right!

Well, it looks like Einstein was right.

If you’re interested in the technical details, have a look at some of these links

Christopher Berry’s blog. Christopher Berry is an LSC member and research fellow at the University of Birmingham, and focuses on what gravitational waves can tell us about compact objects.

Matt Pitkin’s Cosmic Zoo. Matt Pitkin is a research fellow at the University of Glasgow, and works primarily on gravitational wave data analysis in a wide range of ways.

Andrew Williamson’s Cosmoblogy. Andrew Williamson is finishing up his Ph.D  at Cardiff University. He is mostly involved in gravitational wave data analysis, and was also a LIGO Fellow, just like me.

I guess that I should stay off the bat that anything I say here, or anywhere in the blog, is just my own opinion. I don’t claim to represent LIGO in any way. And this post isn’t going to be technical. I will do a technical post in time, so stay tuned.

Here we go!

News that something interesting had happened at LIGO started filtering the the IGR (Institute for Gravitational Research) group at Glasgow on the afternoon of the 14th September 2015. It started out with the more observant email watchers hurriedly shuffling along corridors, diving into an office and closing the door behind them. What they were about to say was both secret to those not within the LSC, and so exciting to those within.

“Have you seen?” or “Did so-and-so tell you yet?” – but it invariably ended with

“There’s been strong signals in the detector! And they think it’s real”



And this was a really, really big deal. Let me tell you why. Advanced LIGO began construction in 2010. Initial LIGO began construction in 1997. Before LIGO, there were Bar Detectors, and they date back as far as the late 1960s. Before then,gravitational waves were only a theoretical phenomenon, not able to feasibly be tested. First theorised in 1916 by Albert Einstein himself, they have remained as one elusive measurement of general relativity. This being the case, when there were whispers of a possible detection, people were very excited indeed.

Now some of us thought that this might just disappear, and for a number of reasons, which I can go into later, but needless to say it didn’t.

Of course, only a few people could be involved with the verification process, and I wasn’t one of them. So all that was going on was on the edge of my radar, but straight ahead was my own work. For a while at a time I would hear nothing about the event, then some information would drip through.

In early November, a small representation of Glasgow’s IGR attended a local astronomy conference, where a small presentation on the future of gravitational wave astronomy was given. It was kinda hard to stay straight-faced. But one little leak and the jig was up.



By late November of 2015, the event was solidly in the territory of “This is happening”. The rumours from [REDACTED] had subsided, and the collaboration ploughed on. Eventually, in late November, the results were shared on an LSC-wide level. In one telecon, we would share information about the source of the event – a binary black hole merger event of 2 medium sized black holes, each a few tens the size the mass of our sun; in another, we would discuss how the detectors were performing at the time of the event, and how they’ve been since.  Also shared was the statistical significance of this event. When you see the plots, it’s really striking how loud this event was compared to the noise that we would expect.



Of course, at the end of November was the centenary of Einstein’s theory of general relativity, of which this discovery is a consequence. A bit fuss was made worldwide, and a few of ius IGRers travelled down to London for a 2 day public event hosted by the Institute of Physics (IOP). We were holding a public outreach stall, focussing on gravitational wave detectors, and their place in physics. It was so hard sitting on this information in front of hundreds of others in the same field. Some of them MUST have known.

Roger Penrose was there as a key speaker. In my undergrad studies in Swansea, I wrote my thesis around the Penrose limit in GR, and its application onto gravitational waves. He would know just how big an announcement this would be. The temptation to tell gets even bigger when people ask bluntly “Have you seen them yet?”. I just wanted to jump up and down yelling “YES! YES! EINSTEIN WAS RIGHT!” — but that would not do. So I composed myself and told them simply the standard scpiel.

“The first observing run of advanced LIGO hasn’t finished yet (only recently finished). It will take some time after the run is complete to check through all the data, but rest assured, all results, even negative ones, will be published in due time”

At about the same time, the detection paper writing committee was named. One fantastic thing about a collaboration of 900+ people is that we can get science like this done. One down side is we almost can’t get anything done. Have you ever tried to decide where to eat with 6 or 7 other people? Isn’t that a nightmare? Imagine nearly a thousand people all trying to write a paper. That would be impossible without some executive decisions, committee thinking, and it has resulted in a really lovely paper, which is a joy to see.

Of course, the paper took time, and there were disagreements. During that period, the LSC-machine chugged away, and excitement mounted.

In January, the paper was all but done, and was shared around the LSC before submitting to the peer reviewers.


And that’s about all the story I have leading up to the moment. But luckily, here I am on site at LHO, with our own little press event!



The press conference starts on Feb 11th at 7.30am here at the Hanford observatory. Knowing that we were about to dawn on a new era of gravitational wave astronomy, I took this picture. It seemed appropriate.

We had to get up at the crack of dawn to be on site before 7. That meant a 5.30 alarm. But the morning flew by, and before I know it, I have coffee and I’m picking at the breakfast spread.

I sit towards the back of the auditorium, where we are live streaming the press conference that was being held in Washington DC (the one everyone thinks whenever I say “Washington”). The excitement was palpable. Not just on site, but seemingly world wide through social media. I guess that I have a selection bias.

You can see the whole press conference here:

At the moment when Dadid Reitze spoke those words, “We have detected gravitational waves”, the room burst into applause. I’m sure everyone who’s ever worked with gravitational wave detection in their lives was smiling from ear to ear at that moment. I know I was. But I mean, I’m new to this. I’m 18 months into my Ph.D. People like Jim HoughKip Thorne, and Rai Weiss have been working in the fields for longer than I’ve been alive! The gratification for these people must have been immense!

It was fantastic to see all of these people, David, Gaby (Gonzalez), Rai, and Kip, giants in the field, speaking about the project I’ve been working towards, about the facility that I was sitting in, and about the this achievement, decades in the making, was really great. They spoke eloquently and to the point. They answered all of the streamed Q&A questions well, and then, the stream finished. It was just about the fastest hour and a half in my life.

Then, our press conference began! You can’t stream that one.


From right to left, the picture shows: Mike Landry, Shiela Dwyer, Kiwamu Izumi, Greg Mendell, Jenne Driggers and Fred Raab. They each spoke to a specific aspect of the lab, the detection, the history and the future, and each had a chance to get questioned briefly after their own segment. It was so obvious that the local press couldn’t wait to jump on this lot for questions.

Now, the press were local. They weren’t necessarily all scientists – so some more than others wanted to know that basics of the science. About how the wave form can lead us to conclude that billions of years ago, black holes inspiralled, or about what is mean by the terms “loud” and “noise” in this context. It seems like we are all so close to the subject, so entrenched in the lingo that it might be a barrier to the wider public.

Between each speaker the press would interject with questions for five or ten minutes, and so the whole press conference took much longer than was expected. But I found it to be a really interesting experience. As the panel went across, the speakers went from overview, to detailed, and back to overview. By the end of speakers’ part, there was seemingly little left to ask.

Fred, the director of LHO, spoke for the longest, and spoke on a wide range of subjects, from the time invested into this discovery, to the astrophysics involved with a merger like this. At one point, he made a comment that cracked me up. The context here is this: in the merger, a black hole of 29 solar masses and a black hole of 35 solar masses. The resulting black hole was not 62 solar masses, but 62. The weight of 3 suns had been radiated away. To that effect,  Fred added something like ‘The most energy ever released by humanity was from the Tsar Bomba, a soviet hydrogen bomb. It released all the energy contained in a 5lb bag of sugar. They realised it was inefficient because you can only kill people so dead’. I couldn’t contain my laughter.

After that was done, we hung around, and I got a chance to meet people. Since I arrived here, I’d not been given a chance to mingle so much, what with everything being so spread out. So it was really valuable to me. But then, as the announcement was early here, it was all said and done by 11. So back to work. The day passed like any other. Well, it tried to, but there was an air of joy about the lab. And media. The phones were ringing all day, and there was always a reporter on site.

In the evening, Mike had invited us to his house for a celebration. There was another reporter there too. She recorded the toast with her microphone. Oh, and the cake. I guess Mike had a cake made specially for the event. Here it is:


In case you can’t make it out, it’s huge! It has plots of the detection printed onto rice paper, as well as the significance of the event on rice paper, with the words “LIGO” and “We Are Listening” piped on top. And it was deilicious.

Again, the party allowed me to make new contacts with my colleagues. Something that a friend back in Glasgow said resonated with me at that party. She said “Working in the IGR is like being part of a family”. I had always disagreed with her. I would think that I kept the relationship professional, that it was all business, and thought nothing more of it. But here I am, thousands of miles away from my Glasgowgroup, in the house of a member of my new, adoptive family I guess. We were celebrating the same thing, I was sure, and I missed my Glasgow family, but I felt so welcomed into the family at Hanford, it didn’t matter.  Of course, I’ll be glad when I get back, but I’m also very glad that I’m here.

For one thing, each grroup has its own personality, its own values, and lets off steam in their own way. Glasgow, for one, likes to network, often on a Friday evening, and often in a pub! It turns out that a fair few members of the team at LHO are musical, which led to, last night, the inception of the Black-hole Binary Bluegrass Band! They played a few tunes last night, in fact, Nutsinee said that she had learned to play the upright bass in a matter of days just for this event!

So after a vew toasts “To the next detection” and “To Hanford always hearing it better” (So, whilst the signal reached the sister observatory, LLO first, and they like to parade that fact, the signal was much more clear at the Hanford observatory),  and some bubbly, we were left to our own devices, but with the need to drive home and get to work for Friday morning, Darkhan and I shuffled home before long.

And I guess that’s the day from my view!


I had distributed the link to the live stream of the press conference among friends and family over facebook. Throughout the presentation, and in the following Q&A, I was fielding questions from my nearest and dearest, as well as words of support, and congratulations. Which, of course, I palmed off. I’m part of the team who did this, but I had no real contribution.

But who knows, one day, I might. This is just the first detection. There are other firsts yet to come. The first detection of GWs from a rotating neutron star, or binary neutron star inspirals, or some real astrophysics done on an ensemble of gravitational wave events.


To read about what others think, try looking at some of these blogs from other LVC members and enthusiasts! I will do a more texhnical post in time, and add the link here!
