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.

Nine years (!) ago today, I was in an extremely crowded lecture theatre with my friends from Astrosoc and Physoc at Glasgow uni (where I was still an undergrad), excitedly waiting for the GW150914 announcement.
Amazing times:')

I’ve detected a honey-butter signal with significance of 6 sigma that fits the expected signature of a binary blueberry merger. Nobel Baking Prize, here I come.

It’s been 10 years since the discovery of GWs was announced to the world! ✨

It’s also Intl Day of Women & Girls in Sci 💜

Here’s something to celebrate both—a symposium ft. women in GW science! 👩‍💻

A promotional poster for the “Glorious Women Symposium” (5–6 March 2026), hosted by LIGO-India Education & Public Outreach and the Inter-University Centre for Astronomy and Astrophysics (IUCAA), with the LIGO India and IUCAA logos at the top. The poster highlights contributions from women scientists in gravitational-wave astronomy and lists program items: eminent speakers from the global collaboration, focus sessions on multidisciplinary GW science, a panel discussion on women representation in GW science, and an interaction session “Ask a Woman GW Scientist.” It notes the event is free, online, and open to all, includes a QR code for registration/details, and lists organisers; the main graphic is a side-profile silhouette filled with illustrations of diverse women.

"LIGO Detects Gravitational Waves from Merging Black Holes"

A beautiful artistic interpretation of our first discovery 10 years ago today

#GW10Years #OTD 🔭🧪🐚
LIGO Detects Gravitational Waves from Merging Black Holes Illustration Credit: LIGO, NSF, Aurore Simonnet (Sonoma State U.) Explanation: Gravitational radiation has been directly detected. The first-ever detection was made by both facilities of the Laser Interferometer Gravitational-Wave Observatory (LIGO) in Washington and Louisiana simultaneously last September. After numerous consistency checks, the resulting 5-sigma discovery was published today. The measured gravitational waves match those expected from two large black holes merging after a death spiral in a distant galaxy, with the resulting new black hole momentarily vibrating in a rapid ringdown. A phenomenon predicted by Einstein, the historic discovery confirms a cornerstone of humanity's understanding of gravity and basic physics. It is also the most direct detection of black holes ever. The featured illustration depicts the two merging black holes with the signal strength of the two detectors over 0.3 seconds superimposed across the bottom. Expected future detections by Advanced LIGO and other gravitational wave detectors may not only confirm the spectacular nature of this measurement but hold tremendous promise of giving humanity a new way to see and explore our universe.
