M82 X-1 is an ultra-luminous X-ray source located in the galaxy M82. It is a candidate intermediate-mass black hole, with the exact mass estimate varying from around 100 to 1000.[1][2][3] One of the most luminous ULXs ever known, its luminosity exceeds the Eddington limit for a stellar mass object.
