The size and spin of black holes can reveal how and where they were born, and gravitational waves offer a way to decode this information like a cosmic DNA test.

Emergence of Calabi–Yau manifolds in high-precision black-hole scattering. Nature, 2025; 641 (8063): 603 DOI: 10.1038/s41586-025-08984-2 ...

Gravitational waves are created whenever massive objects undergo any kind of acceleration. In the case of those first detections, the signal was produced by pairs of black holes within our galaxy ...

An international team of astronomers led by Matus Rybak (Leiden University, Netherlands) has proven, thanks to accidental ...

Researchers announced they have discovered the most massive black hole merger by detecting gravitational waves. Simulating eXtreme Spacetimes via Wikimedia Commons under CC BY-SA 4.0 In 2015, the ...

Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a 225 solar mass behemoth.

Q&A: Astrophysicist explains how black hole mergers and quasars help detect gravitational wave networks by Jim Shelton, Yale University edited by Gaby Clark, reviewed by Andrew Zinin Editors' notes ...

An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as gravitational waves.

The black hole in the heart of the Milky Way, known as Sagittarius A* (pronounced “Sagittarius A-Star”), was discovered in the mid-1970s via its strong radio wave emissions.
