An article published in “The Astrophysical Journal” reports the discovery of a rare intermediate-mass black hole in the Andromeda galaxy at the center of what could be a stripped nucleus, what remains of a galaxy swallowed by Andromeda. A team of researchers observed the star cluster cataloged as B023-G078 at the Gemini Observatory and with the Hubble Space Telescope to calculate the mass distribution within it, a crucial step to understand its nature as a stripped nucleus and identify the intermediate-mass black hole. This could be a way to discover this rare type of black hole, which some models claim merges with others to form supermassive black holes following galaxy mergers.
