2015 was a good year for gravitational-wave astronomy 🔭🧪🛰️ #LPF10anniversary #GW10Years

A coda to Les Guthman's video series about Advanced LIGO, adding an homage to LIGO founder Rainer Weiss.

Our Rapid Response Teams celebrate the end of our fourth observing run. Well done everyone! www.ligo.caltech.edu/news/ligo202... O4 was a success thanks to lots of hard work from across the world. 🔭⚛️🧪

and here's how the O4 end of run looked at Virgo!

This morning marked the end of the fourth LIGO - Virgo - KAGRA observational run's third segment, O4c. Here's how it looked in LIGO Livingston's control room.

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 🔭🧪⚛️☄️

A pair of distant black hole mergers, measured just one month apart in late 2024, are improving how scientists understand the nature and evolution of the most violent deep-space collisions in our universe. www.caltech.edu/about/news/c...

Gabriela González's keynote slides and voice from LLO's Sept 14 anniversary event are up, thanks to Jorge Pullin! #GW10Years

Gabriela González gives the keynote at LIGO Livingston’s celebration of the 10th anniversary of our detection of gravitational waves.

What a difference a decade makes! Announcing the clearest #GravitationalWave detection ever #GW250114 youtu.be/2XmZ8-XQ9jU 📓: doi.org/10.1103/kw5g... 🔭🧪⚛️☄️ #O4IsHere

The loudest #GravitationalWave in #GWTC4 is #GW230814 Detected with only Livingston, it was still about twice as loud as GW150914! Being loud should enable precision tests of general relativity, but with only one detector, you need to be careful with the analysis ligo.org/science-summ... 🔭⚛️☄️🧪

This preview thumbnail hints at all the work that went into taking and calibrating the data being released.

Nice preview of a few paper figures. These big full-collaboration papers are an immense amount of work for which we are all grateful.

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

The LIGO/Virgo/KAGRA GW data from the first big chunk of O4 is releases today. Our catalog paper is here: arxiv.org/abs/2508.18082

This episode of Louisiana Considered includes "An observatory hidden in the woods in Louisiana recently detected a black hole merger. And while it took less than a tenth of a second, it was the largest collision of two black holes ever observed..." www.wwno.org/show/louisia...

It took less than a second for the space observatory hidden in Louisiana woods to detect a black hole that is that is approximately 225 times the mass of the sun.

The LIGO Virgo KAGRA study of #GW231123 was posted to the arXiv today, and is free to read arxiv.org/abs/2507.08219 Data are available from the GW Open Science Center gwosc.org/eventapi/htm... #OpenScience #OpenData ☄️

We are excited to announce the discovery of #GW231123, a gravitational-wave signal from the merger of two high-mass black holes to form one about 190–265 times the mass of our Sun ligo.org/ligo-virgo-k... #O4IsHere 🔭🧪☄️

The @ligo.org - Virgo - KAGRA Collaboration is happy to announce the detection of the merger of the most massive black holes ever observed with gravitational waves 🕳️🕳️

Trump’s proposed cut to giant physics experiment could snuff out new form of astronomy | Science | AAAS www.science.org/content/arti...

Scientists believe if the Trump administration's proposed budget is approved, a Louisiana space observatory could be on the chopping block and see its scientific mission crippled. @theadvocatebr.bsky.social @nolanews.bsky.social www.theadvocate.com/baton_rouge/...

The Louisiana observatory that made a historic scientific breakthrough by detecting gravitational waves from black holes in space in Livingston is now at risk of shutting down from the Trump administration's proposed federal budget cuts.
