Surface brightness of galaxies with emission lines

Abstract

A statistical investigation was made of the distribution of the mean surface brightnesses of galaxies with emission lines. The relative number of these galaxies decreases strongly with decreasing mean surface brightness. A similar effect is observed for compact Zwicky galaxies. The interpretation put forward for this result is that the relative duration of the phase in which emission lines can be formed is correlated to the surface brightness of the galaxies.
