Accretion processes onto black holes: theoretical problems, observational constraints
arXiv:2312.02911
Abstract
We shortly summarize the standard current knowledge on the structure of the accretion flow onto black holes in galactic binary systems and in active galactic nuclei. We stress the similarities and differences between the two types of systems, and we highlight the complementarity of the data caused by these differences. We highlight some new developments and list the unsolved problems.
