Here we report that NGC 3842, the brightest galaxy in a cluster at a distance from Earth of 98 megaparsecs, has a central black hole with a mass of 9.7 billion solar masses, and that a black hole of comparable or greater mass is present in NGC 4889, the brightest galaxy in the Coma...
简介:OJ 287(SMBH) is aextremely large black hole,A smaller 100 million M☉ black hole orbits this one in a 12-year period (see OJ 287 secondary below). But this measurement is in question due to the limited number and precision of observed companion orbits. NGC 1600 质量:(1.7±0.15)...

Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core gravitationally collapses inward upon itself, compressing to a point of zero volume and
Hierarchical mergers are one of the distinctive signatures of binary black hole (BBH) formation through dynamical evolution. Here, we present a fast semi-analytic approach to simulate hierarchical mergers in nuclear star clusters (NSCs), globular clusters (GCs) and young star clusters (YSCs). Hiera...
