For decades, astronomers have been accumulating increasingly strong evidence for the existence of black holes in two distinct mass regimes: “stellar” black holes, weighing a few times the mass of the Sun and “supermassive” black holes with masses ranging from always sitting at the centers of galaxies. There seemed to be nothing in between.
