Description
The existence of gaseous proto-stellar clusters with initial gas mass from one to one hundred million solar masses, and high temperature, primarily composed of atomic hydrogen at the epoch of reionization is strongly supported by cosmological, astrophysical, and recent direct observational evidence. Such systems form from the collapse of a respective compact massive cloud. We consider the possibility of direct formation of a central massive black hole halting the initial collapse. We assume a two component system consisting of a central black hole accreting gas at a steady isotropic state and a gaseous hydrostatic isothermal envelope exceeding to the virial radius of such a massive cloud. We study the thermodynamic equilibria of this system and identify phase transitions from a gaseous phase to a centrally condensed state of a massive black hole with a diluted gaseous atmosphere.
