Black hole debate settled? Stellar-mass black holes found at the heart of the Milky Way's largest star cluster

SMRTR summary

New research suggests that the mysterious movements of stars in Omega Centauri, the largest Milky Way star cluster, are likely caused by a cluster of stellar-mass black holes rather than an intermediate-mass black hole (IMBH). Scientists combined star velocity data with new pulsar acceleration measurements to reach this conclusion. The study helps resolve a long-standing debate and provides insights into black hole formation and star cluster evolution. While an IMBH may still exist in Omega Centauri, it would be smaller than previously thought, weighing less than 6,000 solar masses.
