LIGO might soon turn out even more interesting - as there was observed only 1 (retarded) EM counterpart per ~400 events, and mathematically also advanced solutions are allowed.
More arguments e.g. "too early events", missing SMBHs for PTA (if only retarded): arxiv.org/pdf/2512.20692

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 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.

Plots showing how the new detection compare to our previous observations. The top panel shows all the events from the LVK’s most recently published catalog, GWTC-4.0, and our two new events GW241011 and GW241110 ordered by the primary spin projected in the direction of the spin of the orbital plane — in other words, how aligned the primary black hole’s spin direction is with the binary system’s orbit direction. Values greater than zero means the black hole is aligned with the spin of the orbit, whereas less than zero means the system is anti-aligned. The bottom panel shows the distribution of primary mass (the mass of the larger black hole) in solar masses and the mass ratio of the black hole pair for all events from GWTC-4.0 including our new events.
Our new paper on our LIGO @egovirgo.bsky.social KAGRA discovery of #GW241011 and #GW241110 is now published

Screenshot: 1. Proving Einstein right! The first gravitational wave detection. On Sept. 14, 2015, ripples in space-time washed over Earth that were generated by the merger of two black holes, each with a mass of around 30 times that of the sun. This signal, which would come to be known as GW150914 (GW for "gravitational wave" and the following numbers for the date of measurement), had been traveling to our planet for 1.4 billion years. GW150914's arrival and detection confirmed a theory that was first proposed a century earlier by arguably history's most famous physicist, Albert Einstein, in his 1915 theory of gravity, general relativity.
Screenshot: 10. Proving Einstein ... wrong!?! The LIGO project operates two detector sites: one near Hanford in eastern Washington, and another near Livingston, Louisiana (shown here). The observatory has four kilometre arms, long concrete tubes surrounded by the greenery of Louisiana. The central building shines white in the middle of the picture. There is LIGO's Science Education Center there is you would like to visit.
