Both black hole accretion and galaxy formation and evolution are important research topics in astrophysics. They focus on quite different scales and both have been intensively studied.
Black Holes, dense star clusters, and galactic nuclei move into the focus of cosmological galaxy formation and evolution. High-resolution observations as well as simulations, in our local environment as well as in the distant universe approach the central engine and its co-evolution with stars and gas around. Black Holes formed in astrophysical environments are expected gravitational wave sources. Continua a leggere IAU 312: Star Clusters and Black Holes in Galaxies Across Cosmic Time
