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.

Are all quasars galaxies?
A quasar is not a galaxy. A quasar is an intense energy source associated with a supermassive black hole that is actively feeding. All quasars are located at the centers of galaxies.
Why does Sagittarius A indicate that a black hole is at the center of the universe?
Sorry, the universe does not have one center. According to the usual interpretation of the Big Bang theory, any and all points in the universe can equally be considered centers of the universe.Perhaps you meant to ask "Why does Sagittarius A indicate that a black hole is at the center of the Milky Way Galaxy?" instead. Galaxies do have distinct centers, all spiral galaxies are now believed to have a supermassive black hole at their centers, and our galaxy: the Milky Way is a spiral galaxy. The observations of the object called Sagittarius A match what would be expected of a supermassive black hole and are in the right galactic direction to place it at the center of the Milky Way galaxy.
What is the black-hole in the galaxy?
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 .
Are quasars part of your solar system?
No. Quasars are at the centers of distant galaxies.
How are super-massive black-holes in the center of galaxies?
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.
What is in the center of the galaxy?
All galaxies have supermassive black holes in their centers.
Are all quasars galaxies?
A quasar is not a galaxy. A quasar is an intense energy source associated with a supermassive black hole that is actively feeding. All quasars are located at the centers of galaxies.
Where did a black hole come from?
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.
Can the earth move into the center of the milky way?
No, and that's a good thing, because scientists now believe that a supermassive black hole occupies the centers of most large galaxies.
Are the most massive and densest singular objects in the universe?
Probably the supermassive black holes that are believed to be at the centers of many (perhaps most) large galaxies. These may be related to quasars.
Where are black holes generally found in a galaxy?
Most or all galaxies appear to have supermassive black holes at their centers and probably have stellar mass black holes scattered throughout.
Is the center the densest part of the Milky Way?
Probably yes, although we cannot be certain. The gas and dust clouds prevent us from seeing the center. Scientists believe that there may be a supermassive black hole at the center of the Milky Way, as there appear to be supermassive black holes at the centers of many large galaxies.
Is there any black hole near your galaxy?
Yes, probably many of them. We believe that there is a supermassive black hole at the center of the Milky Way galaxy; that there are probably similar suoermassive black holes at the centers of many large galaxies.

What are distant galaxies with black holes in their centers called?
There have been some suggestions that the objects called quasars might be extremely active galaxies with unusually supermassive black holes at their centers at such great distance from us that it is not possible for telescopes to resolve their galactic structure, making them just look like very bright stars (quasi-stellar objects). However this has not been verified.If these suggestions are correct, these extremely active galaxies must be so distant that the light we are seeing from them must have been emitted only a short time after the big bang began, in the initial cycle of star formation, which would make them the earliest galaxies formed and likely very young galaxies. However if they are this young these extremely active galaxies might have galactic structures so different from the galaxies we are familiar with that even if our telescopes could resolve them, we might not recognize them as galaxies.
How are the centers of many spiral galaxies similar to many elliptical galaxies?
Both have a huge black hole at their center.
