Qualitative analysis of a cosmological evolution in a hydrodynamical model with a barotropic equation of state

Abstract

INITIAL LUMINOSITY FUNCTIONS OF STARBURST GALAXIESFor the sample of about 800 starburst galaxies the initial luminosity functions which appear the distributions of galaxy luminosities at zero starburst age are considered based on the data of luminosities of galaxies in the recombination Нα emission line in the regions of ionised hydrogen and the ultraviolet continuum. We find the initial luminosity functions for the starburst galaxies with Нα emission and ultraviolet continuum are satisfactory approximated with log-normal function.
