Happy 10th launch anniversary, LISA Pathfinder! 🥳 For the first time ever, this mission tested in space the technology needed to detect gravitational waves, which paved the way to LISA 🤜 🤛 Planned to launch in 2035, LISA will be first gravitational wave detector in space 👉 esa.int/lisa 🔭

Happy birthday GW150914! When you were detected I was still an undergrad looking to get into GWs for her PhD (it's important to my internal story of myself that I wanted to do this *before* the detection) It's hard to believe how far we've come since then. 🐡🧪🔭 #GW10Years

Exactly 10 years ago, the signal of a gravitational wave from the merger of two black holes arrived on Earth. It was not a special signal, but one like many that had always reached our planet. On that day, however, for the first time humankind was ready to listen to it. (1/7)

New results out today from LIGO (@ligo.org) - Virgo (@egovirgo.bsky.social) - KAGRA ! The latest catalogue features more than double the number of probable signals compared to the previous one! #GWTC4 paper: arxiv.org/abs/2508.18082

Results from the first part of our fourth LIGO @egovirgo.bsky.social KAGRA observing run are out today! We're pleased to share the largest catalog of gravitational-wave observations with more discoveries of black holes and neutron stars 📰 arxiv.org/abs/2508.18082 🔭🧪⚛️☄️ #GWTC4

New masses in the stellar graveyard plot, showing astronomical observations of black holes and neutron stars. The number of gravitational-wave observations of black holes is overwhelming. The plot is arranged to look nice, the horizontal axis has no meaning, but the vertical one shows masses. We have a significant range of masses from about 1 solar mass to over 200 solar masses for our largest merger remnant. New out today is a neutron star black hole binary GW230518_125908, as well as a lot of binary black holes.

Today at Carole Mundell's (@cmundell.bsky.social ) a few familiar objects can be spotted! This mosaic shows a #GravitationalWave signal in time and frequency @uofgravity.bsky.social Check out the story behind the first mosaic here: (page 17) ligo.org/wp-content/u...
