Accurate mass of supermassive black hole calculated by astronomers using ALMA
... most distant one known can be found in a quasar galaxy billions of light years away. To determine the actual mass of a supermassive black hole, researchers measure the speed of the orbiting material, stars and clouds of gas, that swarm around...

A recently discovered stellar black hole could be the most massive yet, say astronomers
... Sun. Furthermore, if the black hole is spinning or the disk is inclined, the black hole mass will become still larger. The existence of such massive black holes has been confirmed via gravitational wave detections due to black hole merger, but they...

Mass of black holes determines star formation history
... explained. "For galaxies with the same mass of stars but different black hole mass in the center, those galaxies with bigger black holes were quenched earlier and faster than those with smaller black holes. So star formation lasted longer in those...

Astronomers detect a rare type of object known as a spiral DRAGN
... in MCG+07-47-10, a face-on late-type Sbc galaxy with distinctive spiral arms and prominent bulge suggesting a high black hole mass. This DRAGN, found with the Giant Meterwave Radio Telescope, however has a comparatively low radio luminosity...
