FORMATION OF PRIMORDIAL LUMINOUS OBJECTS IN VIRIALIZING HALOS
Abstract:In the framework of a simplified description we analyze the question of how shock waves, possibly formed in the process of virialization of dark matter halos, affect evolution of low-mass baryonic condensations. We argue that such shock waves initiate fluctuations of temperature and associated variations in fractional ionization, which in turn can diminish the minimal mass of the first luminous objects by factor of 30.
