JWST Sees Smoking Gun for Black Hole Mergers in the Virgo Cluster
A pair of dwarf galaxies in the giant Virgo Cluster show what can happen when these stellar cities interact. Scientists at the University of Michigan focused the James Webb Space Telescope (JWST) onto the galaxies NGC 4486B and UCD736 and found each of them sporting "overmassive" black holes at or near their hearts. Those supermassive black holes comprise a large fraction of each galaxy's mass.
