I know that I'm most galaxies black holes live in the center. I'm wondering if this is true for Galaxy clusters. Are there black holes in the center of galaxy clusters?
I can't say for sure but I see absolutely no reason why we should expect for there to be. The formation of galaxies is very likely tied up with the central SMBH in some as yet unknown way, but clusters of galaxies would not seem to need them.BadgerBadger92 said:I know that I'm most galaxies black holes live in the center.

PeterDonis said:Creating a black hole is not a matter of having "enough mass". Black holes can be of any mass. What is required is to have enough mass in a very small volume.
We do not know exactly how the supermassive black holes at the centers of galaxies formed, but a plausible scenario is that the stars at the centers of galaxies formed individual black holes by gravitational collapse, and then those holes gradually merged into the supermassive ones we see at the centers of galaxies now. This is plausible because stars at the centers of galaxies are close enough together that you can get enough mass in a small enough volume.
A similar scenario does not work for galaxy clusters because individual galaxies in a cluster are too far apart, and there is no plausible way for the holes at the centers of galaxies to merge into larger ones.
A black hole is a region in space with a gravitational pull so strong that nothing, including light, can escape it. This occurs when a massive star dies and collapses in on itself, creating a singularity.
Yes, black holes are very common in galaxy clusters. In fact, most large galaxies, including our own Milky Way, have a supermassive black hole at their center. Additionally, many smaller black holes can also be found within galaxy clusters.
Black holes in galaxy clusters can be detected through various methods, including observing the effects of their strong gravity on surrounding matter, detecting X-rays emitted from hot gas falling into the black hole, and observing the distortion of light from objects passing near the black hole.
No, black holes in galaxy clusters can vary greatly in size. While supermassive black holes at the center of galaxies can have masses equivalent to billions of suns, smaller black holes within the cluster can have masses equivalent to just a few suns.
Black holes play a crucial role in galaxy clusters by regulating the growth of galaxies. As matter falls into a black hole, it can release large amounts of energy, which can influence the formation and evolution of surrounding galaxies. Black holes also play a role in the distribution and movement of matter within the cluster.
