We are pleased to announce our discovery of #GW241011 and #GW241110 Both come from binary black holes where one black hole is much larger than the other. The larger black holes have large spin. Could these black holes have formed in a previous merger? ligo.org/science-summ... #O4IsHere 🔭🧪⚛️☄️

Today we celebrate the 10th anniversary of the first detection of gravitational waves by @ligo.org 🎉 Research by members of the Gravity Exploration Institute in Cardiff helped lay the foundation for that detection, which opened an exciting new window to the universe. Read more about it here:

Several members from Cardiff's Gravity Exploration Institute will be taking part in this special gravitational wave science ceilidh (traditional Scottish dance) in Glasgow this week!

Prof Stephen Fairhurst of the Gravity Exploration Institute in Cardiff is the new spokesperson for the LIGO Scientific Collaboration! He is the first person from a non-US institution to hold this position. We are very pleased and proud that his many years of work within the LSC have been recognised.

🎉 We have reached 200 #GravitationalWave candidates in O4! 🎉 The fourth observing run (O4) of our detector network has had the best performance so far, with more candidates than ever before! We are currently busy analysing all these wonderful data and look forward to sharing results #O4IsHere 🔭☄️

Nine years ago we announced to the world that we have detected #GravitationalWaves we did it! youtu.be/lslUF9gdYI8

A recent paper from the GEI presents the first convolutional neural network (CNN) analysis pipeline for the detection of generic transient gravitational waves signals, with sensitivity across a wide range of signal parameters, used for real-time searches in data from the LIGO and Virgo detectors.

Happy New Year! Blwyddyn Newydd Dda!

The first Gregynog Relativity Workshop was held at Gregynog Hall in Mid Wales, September 1-3, 1975. The topic was Thermodynamic Properties of Gravitational Fields. #flashbackfriday When Bernard Schutz @bschutz.bsky.social moved to Cardiff in 1974, he began to organize workshops where...
