Clashing stars form an intermediate-mass black hole

Zoom-in of a snapshot taken from one of the DRAGON-II simulations, a series of models representing dense star clusters with up to 1 million stars. Here, yellow and orange points represents stars similar to the Sun -- slightly lighter, slightly heavier -- whilst dark and light blue points represent stars more massive than 20and 300 times our Sun, respectively, being the progenitors of white dwarfs, neutron stars, and black holes. The big white spot represents a very massive star, weighing 350 solar masses, which in short time will collapse to an intermediate-mass black hole, an elusive type of black holes that may link black holes coming from the death of massive stars and the gargantuan black holes sitting at the centre of almost all galaxies (Link to the publication: https://academic.oup.com/mnras/article-lookup/doi/10.1093/mnras/stad2292)
