Yes. Some galaxies, particularly irregular galaxies, appear to lack supermassive black holes.
Supermassive black holes found at the centers of galaxies are related to the stellar velocity dispersion in the bulge of the galaxy. To a lesser degree, there is also a correlation with the mass of the galaxy.
No, only small ones, the supermassive ones are at the centre of galaxies.
Almost every galaxy has a super massive black hole in its centre and this fact is widely accepted now days . Milky way galaxy also have a super massive black hole of its own, weighing more than 4 million times more than our sun's mass. Andromeda galaxy is our nearest neighbour having a super massive black hole in its centre weighing 114 million solar masses .
millions of black holes are in all of the galaxies, and in the center of all large galaxies is an enormous black hole that makes all the stars go around it. the power was a million times greater 350 years ago. this cycle will repeat over again. Scientists have come to believe that there is very probably a supermassive black hole in the center of the Milky Way, and that there may be supermassive black holes at the centers of many galaxies.
A black hole has a much larger mass than a planet. The mass of a black hole, however, is contained in a point that is smaller than some fundamental particles. The event horizon of a typical stellar mass black hole is much smaller than any planet, but the event horizons of supermassive black holes are much larger.
Yes
Most black holes form when massive stars exhaust their fuel and their cores collapse. There are also supermassive black holes at the centers of most galaxies. Scientists are not sure how supermassive black holes form.
Black Holes are scattered throughout the cosmos. It is theorised that there are supermassive black holes at the centre of galaxies such as ours (The Milky Way).
Not sure what you mean. M60 is a galaxy. Just about all galaxies have supermassive black holes in their center - and lots of smaller black holes. The supermassive black hole in M60 is estimated to have 4.5 billion solar masses - one of the largest known black holes.
Most or all galaxies appear to have supermassive black holes at their centers and probably have stellar mass black holes scattered throughout.
Supermassive black holes found at the centers of galaxies are related to the stellar velocity dispersion in the bulge of the galaxy. To a lesser degree, there is also a correlation with the mass of the galaxy.
All galaxies have supermassive black holes in their centers.
Quasars are related to supermassive black holes in the center of galaxies.
It depends, Black holes can go from being microscopic to supermassive black holes that entire galaxies revolve around. It all depends on which black hole and which quasar.
Most galaxies - the larger ones at least - have a supermassive black holes in their center.
No, only small ones, the supermassive ones are at the centre of galaxies.
In their mass. a "stellar black hole" has a few solar masses (a few times the mass of our Sun), while a supermassive black hole (found in the center of most galaxies) typically has a mass of millions or billions times the mass of our Sun.
