The #GR24Amaldi16 art gallery is now online! Some really amazing pieces on display - I especially like the papier mâché and clay one by Riccardo Buscicchio (And of course all of @theastrophoenix.bsky.social's art but does that need to be said?) 🐡🔭🧪 uofgravity.github.io/amaldi-art/

Researchers from @uofgphysastro.bsky.social & @uofgravity.bsky.social are celebrating the 10th anniversary of @ligo.org's historic first detection of gravitational waves. Learn more the team’s role in the detection and their ongoing research: gla.ac/45Yeusr

Happy birthday to GW150914, our first (of many) #GravitationalWave discoveries, detected 10 years ago today! #GW10Years 🧪⚛️🔭 🖼️: @chirpmass.bsky.social

This is more like the generation I know from teaching—they want to build a better future, not regress

It was a good cake

This is a wonderful mini (< 10 min) documentary about @ligo.org and the first gravitational wave detection 10 (!) years ago, made by my former colleagues at @uofgravity.bsky.social. I love the inclusion of all the broader scientific applications of the technology. youtu.be/SqhFtkQ4f2c?...

Which is your favourite amongst our detections? #GW10Years 🧪🔭⚛️

GW170104 always has a special place in my heart. It is always so well behaved to analyse GW150914, GW200129, GW230814 and GW250114 are wonderfully clear, and rightly deserve their limelight GW191219 is my guilty pick. Such an intriguing source, but so many uncertainties #GW10Years

Absolutely stunning observations. Progress in the last few years has been amazing, never have we had such wonderful astronomical data

Friday #GravitationalWave candidate #S250912f If real, the source is probably a binary black hole (chirp mass ~44–88 solar masses) False alarm rate 1 per 1.1×10^5 yr GraceDB gracedb.ligo.org/superevents/... GCN gcn.nasa.gov/circulars/41... gcn.nasa.gov/circulars/41... Rating 🐠🍫🐚 [🧪🔭⚛️]

The Kerr solution is truly remarkable. A mathematical description of black holes with just two parameters—this would make black holes the simplest macroscopic objects in the Universe. And all our observations show that this does describe astrophysical black holes as far as we can tell 🔭⚛️🧪

Our detailed study of #GW230814 is out arxiv.org/abs/2509.07348 We can precisely test general relativity with this loud signal. Most tests show agreement with Einstein's theory, but some… The deviations can be explained by detector noise. Having multiple detectors is important! 🔭🧪⚛️☄️ #GWTC4

#GW230814 is such a beautifully loud signal. An signal-to-noise ration of 42 using just one detector! That is louder than GW170817 observed with three. It is amazing the progress the detectors are making, and the science that these measurements can bring 🧪⚛️☄️🔭

One can still look for flowers in the rain.

LIGO has the coolest science. The fact that my phone sometimes buzzes in my pocket in response to a black hole merger somewhere outside our galaxy is just amazing.

And far too often we still think physics is just quantum mechanics and cosmology - far away mysterious things that don't relate to our everyday life. That's nonsense. Why it is tiring to walk slowly, what limits the height of a tree, why do baby ducks swim in a tight line? Physics will tell you!

This, from the Quakers, is a pretty good example of how to resist pressure from bigot lobbying groups. Effectively “we legally can allow trans people to use the loo, we morally should, and we tried it and nothing bad happened”

Solar seems like a good investment

Rai was also enthusiastic, always keen to engage with new ideas. His mentorship in the field will be much missed, as will his keen insights.

We've been busy. I hope everyone likes black holes! (We have a couple of neutron stars too)

And speaking of art: Squirrel with a Pearl Earring. (I don’t know the name of the artist but a friend shared this one on her Instagram)

Gotta love a chirp you can see by eye! Look at GW230814, it is a beast! GW230814 is our loudest published gravitational-wave, beating the previous record-holder GW170817. It is the highest signal-to-noise ratio even though it was only observed with a single detector. 🔭🧪☄️

Researchers from @uofgravity.bsky.social and @uofgphysastro.bsky.social led the analysis of data from 128 gravitational wave detections made by the LIGO-Virgo-KAGRA Collaboration. Read more about the results, published in a new preprint catalogue paper, here: www.gla.ac.uk/news/headlin...
