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

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.

I refuse to accept that it's been TEN YEARS since I sat in that room ๐Ÿ˜ญ

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:')

Iโ€™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.

10 years ago today, our discovery paper was published in Physical Review Letters

doi.org/10.1103/Phys...

It has gone on to be highly cited. But it has also had an impact outside of academiaโ€”its @altmetric.com is in the top 1000

Itโ€™s been 10 years since the discovery of GWs was announced to the world! โœจ

Itโ€™s also Intl Day of Women & Girls in Sci ๐Ÿ’œ

Hereโ€™s something to celebrate bothโ€”a symposium ft. women in GW science! ๐Ÿ‘ฉโ€๐Ÿ’ป

A promotional poster for the โ€œGlorious Women Symposiumโ€ (5โ€“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 โ€œAsk a Woman GW Scientist.โ€ 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.
