When two supermassive black holes collide during a merger of galaxies, we expect them to release gravitational waves - fluctuations in the fabric of spacetime. Simulations predict that these mergers, unlike those of their stellar-mass counterparts, emit both gravitational waves and radiation - the latter originating in the hot, interstellar

"The black holes orbit each other and lose orbital energy by emitting strong gravitational waves, and this causes their orbits to shrink. The black holes spiral toward each other and eventually merge," said Goddard astrophysicist John Baker. Close to these titanic, rapidly moving masses, space and time become repeatedly flexed and warped.

A computer simulation shows the collision of two black holes, a tremendously powerful event detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, or LIGO. LIGO detected gravitational waves, or ripples in space and time generated as the black holes spiraled in toward each other, collided, and merged.

The amount of information produced by the coalescence of two black holes can only amount to about 30% of the mutual information contained in the two black holes.

In their brief research letter, the researchers say that these mergers are a window into Hawking Radiation (HR.) When black holes merge, they may create so-called "morsel" black holes the size

https://astronomy.stackexchange.com/questions/51533/how-do-two-black-holes-merge
The shape of the event horizons is determined by the solutions of the General relativity equations, and the event horizons for two black holes are not spherical. So the event horizons merge in space time, and the merged blackhole rapidly (over a few hundreds of milliseconds) settles down to a state that is asymptotically the same as a single

Simulation: Two Black Holes Merge Simulation Credit: Simulating eXtreme Spacetimes Project Explanation: Relax and watch two black holes merge. Inspired by the first direct detection of gravitational waves in 2015, this simulation plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage, the black holes are posed in front of stars, gas, and dust.

https://physics.stackexchange.com/questions/20690/what-happens-to-information-when-black-holes-merge
Physically, the black hole horizons join together to make a new horizon, but the process of connecting is not classically realizable (it takes an infinite time for each black hole to fall into the other, from the exterior point of view). Physically all this doesn't matter--- the black holes merge into one like soap bubbles merging.

https://astronomy.stackexchange.com/questions/13895/what-happens-to-the-information-on-the-event-horizons-of-two-merging-black-holes
When two black holes merge, they form a black hole of smaller mass than the combined masses. Once more the total surface area of the event horizons has decreased to that of the event horizon of the new black hole, so information must have been 'radiated'. ... So what happens when two masses with enormous gravity pull on each other? The stronger

https://physics.stackexchange.com/questions/402051/what-happens-to-the-singularities-of-two-black-holes-in-the-moment-they-merger
In any black hole, we can't really localize the mass. The difference between a Schwarzschild black hole and an astrophysical one is that a Schwarzschild black hole has always existed. It didn't form by gravitational collapse. While in (i) [a Schwarzschild black hole] the singularities which contain the masses are a point in time

https://physics.stackexchange.com/questions/277073/what-happens-to-the-angular-momentum-of-two-merging-black-holes
When the black holes are separated by of order $\leq 10^5 r_s$ (for stellar mass black holes), the timescale for doing so becomes less than billions of years. The angular momenta of the individual or final black holes are quite negligible compared to this until the very final stages of merger.

https://phys.org/news/2024-05-black-holes-particles.html
Each black hole has particle jets in two opposing directions. As those jets push away gas and dust, they open up a pocket in space surrounding the black hole. These are visible in the X-ray data
