The Universe’s biggest black holes may be forged in violent mergers

Gravitational-Wave Data Suggest the Biggest Black Holes Are Built Through Repeated Collisions

A new analysis of black hole mergers in the LIGO-Virgo-KAGRA catalog points to a separate population of very massive, rapidly spinning black holes formed through hierarchical mergers.

Key Takeaways

Researchers analyzed 153 reliable black hole merger detections from GWTC4.
The most massive black holes appear to form through hierarchical mergers.

Black-hole census strengthens the case for a long-predicted forbidden gap

New research argues that pair-instability supernovae may explain why stellar black holes in a wide mass range appear to be unexpectedly rare.

Key Takeaways

New research argues that pair-instability supernovae help explain a predicted black-hole mass gap.
Gravitational-wave detections now provide a growing census of black-hole masses.

Black hole merger data may be exposing one of the universe’s most violent stellar deaths

A new analysis of gravitational-wave detections suggests a missing band of black hole masses, supporting the idea that some massive stars explode so completely they leave nothing behind.

Key Takeaways

Researchers say merger data hints at a gap in black hole masses.
That gap matches models in which some massive stars are destroyed in pair-instability supernovae.

Black Hole Merger Ripples Spacetime—and May Have Flashed in Gamma Rays

Astronomers detected gravitational waves from a massive black hole merger in November 2024, followed seconds later by a short gamma-ray burst—potentially the second confirmed multi-messenger cosmic event in history.
