Omega Centauri Unveils Its First Hidden Stellar-Mass Black Hole
TL;DR Summary
Astronomers using over two decades of Hubble data and JWST observations have confirmed the first stellar-mass black hole in the Omega Centauri globular cluster, designated oMEGACat BH-2, with a mass of 4.46 solar masses orbiting a sun-like star every 94 years. The finding suggests Omega Centauri could host a large hidden population of such black holes and highlights astrometry as a key method, with plans to find more using Roman Space Telescope in the future.
