It appears that the relationship between nuclear black hole mass and other properties of late - type galaxies remains to be understood. (greenbankobservatory.org)
The quasar, with its central black hole mass of 12 billion solar masses and the luminosity of 420 trillion suns, is at a distance of 12.8 billion light - years from Earth. (sciencedaily.com)
But, in the early universe, their study shows that the 3C 298 galaxy is 100 times less massive than it should be given its behemoth supermassive black hole mass. (keckobservatory.org)
