NGC 2766-3c
(Preview)
Chandra Finds Intriguing Member of Black Hole Family Tree Astronomers have combined the X-ray and radio data to determine that NGC 2766-3c is likely an intermediate-mass black hole (IMBH). As the name suggests, IMBHs are black holes that are larger than stellar-mass black holes that contain abou...
