Web30 de sept. de 2024 · The supermassive black holes — black holes of millions to tens of billions of solar masses — that lurk at the active centers of galaxies have a peculiar quirk: their masses correlate with the stellar masses of their hosts. This means that the larger a galaxy is, the larger we can expect its central black hole to be. But why the connection? WebThe black hole is mostly empty, and all the mass is concentrated within a tiny region (clasically a point) in the center of the black hole. If you ignore this and pretend a black hole of mass M and volume V ∝ r 3 had a uniform density ρ then you can calculate it, simply using ρ = M / V.
