At first glance, this galaxy appears to be a normal spiral galaxy, much like the Milky Way – which has a supermassive black hole at its center. But some galaxies are centered on lighter, intermediate-mass black holes. RX J1140.1+0307 is such a galaxy. In fact, it is centered on one of the lowest black hole masses known in any luminous galactic core.
