List of black holes : ウィキペディア英語版 | List of black holes
This is a list of black holes (and stars considered probable candidates) organized by size (including black hole stars 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. ==Supermassive black holes and candidates==
