When Black Holes Eat Their Own

When Black Holes Eat Their Own

Black holes are eating each other and growing fat on the remains! They then seem to move on, finding new partners to devour in what can only be described as a cycle of violence. Two gravitational wave detections from late 2024 have caught these “second generation" black holes in the act, one spinning so fast it ranks among the most extreme ever observed, the other rotating backwards. These aren't simple collisions between black holes born from d…

Not Their First Rodeo: Gravitational Wave Detectors Spot Merging Black Holes That Have Merged Before

The gravitational wave events GW241011 and GW241110 provide strong evidence for the growth of black holes through successive mergers.

Pair of black hole mergers sheds new light on their formation, evolution

In a new paper published Oct. 28 in The Astrophysical Journal Letters, the international LIGO-Virgo-KAGRA Collaboration reports on the detection of two gravitational wave events in October and November of last year with unusual black hole spins.

Colliding black holes might have formed from earlier cosmic smashups

28.10.2025 - A pair of distant black hole mergers, measured just one month apart in late 2024, are improving how scientists understand the nature and evolution of the most violent deep-space collisions in our universe.
