List of black holes
List of some black holes From Wikipedia, the free encyclopedia
This list of black holes (and stars considered probable candidates) is organized by mass (including black holes of undetermined mass); some items in this list are galaxies or star clusters that are believed to be organized around a black hole. Messier and New General Catalogue designations are given where possible.

Black holes detected by gravitational wave signals
As of February 2019[update], 10 mergers of binary black holes have been observed. In each case two black holes merged to a larger black hole. In addition, one neutron star merger has been observed (GW170817), forming a black hole. In addition, over 30 alerts have been issued since April 2019, of black hole merger candidates.
Multiple black hole systems
Binary black holes
- EGSD2 J142033.66 525917.5 core black holes — galaxy hosting a dual AGN[20]
- OJ 287 core black holes — a BL Lac object with a candidate binary supermassive black hole core system[21]
- PG 1302-102 – the first binary-cored quasar — a pair of supermassive black holes at the core of this quasar[22][23]
- SDSS J120136.02+300305.5 core black holes — a pair of supermassive black holes at the centre of this galaxy[24]
In addition, the signal of several binary black holes merging into a single black hole and in so doing producing gravitational waves have been observed by the LIGO instrument. These are listed above in the section Black holes detected by gravitational wave signals.
Trinary black holes
As of 2014, there are 5 triple black hole systems known.[25]
- SDSS J150243.09+111557.3 (SDSS J1502+1115) core black holes — the three components are distant tertiary J1502P, and the close binary pair J1502S composed of J1502SE and J1502SW[25]
- GOODS J123652.77+621354.7 core black holes of triple-clump galaxy[26]
- 2MASX J10270057+1749001 (SDSS J1027+1749) core black holes[27]
