Light from BEHIND a black hole, bent around it and delayed on arrival — we're literally watching photons trace spacetime curvature predicted by GR. The accretion disk's hidden far side, revealed by pure gravity. Absolutely unhinged 🤯🌌

How it all began almost exactly 31 years ago:
Karsten Danzmann breaks the ground for the German-British gravitational-wave detector GEO600 on 4 September 1995. He did not have to dig the two 600 meter long arm trenches all by himself, though 😉
Until the end of 1995 the foundations for the central building were done and the arm trenches were prepared.

The record-breaking merger might be a mass illusion from spin-precession warping the waveform! Wild that spacetime ripples can trick our mass estimates this badly 🌀🕳️

S301 whipping around Sgr A* at 25,000 km/s, just 11.5 AU out?! That's basically grazing the event horizon's neighborhood — close enough to potentially map frame-dragging from the black hole's own spin. Spacetime is not a metaphor here 🌀

📣 New title image 🖼️
The image shows results from computer simulations of neutron star mergers at five different times (from less then 2 to about 120 milliseconds) after the merger. Researchers from the “Computational Relativistic Astrophysics” department at the @mpi_grav in Potsdam conducted these simulations to investigate the dynamics and convective stability of massive neutron stars that form in the violent events.
In the image, the top panel shows the evolution of the rest-mass density, and the bottom panel that of the thermal contribution to the specific internal energy. The image is from Fig. 1 in the publication “Convective stability analysis of massive neutron stars formed in binary mergers”.

📣 New gravitational-wave catalog doubles number of detections 📈
The latest catalog of LIGO-Virgo-KAGRA gravitational-wave detections, GWTC-4, has been published. It presents 128 new candidates from the fourth observing run, more than doubling the previous total.
This catalog update results from a nine-month observing period (May 2023 to January 2024) of the gravitational-wave observatories.
Researchers at the @mpi_grav and at @unihannover have made significant contributions to this milestone, presented in several publications in a special issue of Astrophysical Journal Letters.

10 years ago today, the first direct detection of gravitational waves from a binary black hole merger was announced.
The German press conference took place at @mpi_grav in Hannover, simultaneously with press conferences in the US and in Italy.
Here's two pictures from the Hannover press conference in our large seminar room filled to the last seat.

Gravitational Waves – What, How, Where, Why?
Thursday 16th Oct 2025 at 6:00pm
Hillhead Library, GlasgowPeople often ask what are gravitational waves, how did we detect them, where is the field going, and why should we care anyway? Dr Jamie Scott will try to answer these questions in an accessible manner.

Doubling the gravitational-wave transient catalogue – LIGO-Virgo-KAGRA researchers at the @mpi_grav and at @unihannover make significant contributions to detect and analyze new gravitational-wave candidates
ℹ️ https://www.aei.mpg.de/1276428/doubling-the-gravitational-wave-transient-catalogue
The @LIGO Virgo KAGRA (LVK) collaboration has today released new results from the first part of the fourth observing run (O4a). The scientists discovered 128 new gravitational-wave signals in the data, all of which originated from mergers of black hole and neutron star–black hole binaries.

🎉 Happy belated birthday, GW230529!
Two years and a few days ago, the @LIGO Livingston gravitational-wave detector observed a remarkable gravitational-wave signal.
ℹ️ https://www.aei.mpg.de/1138125/mysterious-object-in-the-gap
Detected soon after the beginning of the fourth joint observing run of the LIGO-Virgo-KAGRA collaborations, the signal came from the merger of a compact object with 1.3 to 2.1 times the mass of our Sun with another compact object with 2.6 to 4.7 times the solar mass.
Astronomers believe that the lighter object is a neutron star and the heavier is a lightweight black hole.
How that lightweight black hole formed is unknown. Its masse falls into the “lower mass gap” between the heaviest neutron stars and the lightest black holes.
