GW231123: LIGO-Virgo-KAGRA detect most massive black hole merger to date

Gravitational waves from massive black holes challenge current astrophysical models

Visualization showing the merger of two massive black holes, illustrating the gravitational wave observation named GW231123. The merging black holes are about 132 and 106 times as massive as our Sun, the most massive ones observed by the LIGO/Virgo/KAGRA detectors so far.

Simulation of the binary black hole merger GW231123

The video and the images display the numerical simulation results of a binary black hole merger consistent with the gravitational-wave event GW231123. 

The inset near the top right shows the two black holes orbiting around other and merging into one larger black hole. The main panel shows a wider perspective with the black holes at the centre of the frame, surrounded by their gravitational waves, which are propagating away at the speed of light. Dark blue colors represent comparatively weak gravitational waves, whereas yellow colors represent the strongest waves emitted near merger. The black holes are strongly rotating, flattening their horizons, and causing the plane of their orbit and their individual rotation axes to change. The visualisation artificially colors the northern hemispheres of each black hole in a lighter shading of grey, to make these changes visible. The bottom of the visualisation shows the gravitational waveform that would be recorded by a gravitational-wave detector situated next to the camera.
