Abstract

Recent redshift surveys have shown that the excess galaxies seen in faint galaxy number counts (above those expected, given the local galaxy luminosity function) are not evolved giants at high redshifts, but low- to moderate-luminosity objects at more modest redshifts. This has led to the suggestion that there was once an additional population of dwarf galaxies which has since disappeared, i.e. there is non-conservation of galaxy number. Here we investigate the possibility that these disappearing dwarfs have actually evolved to become the population of very low surface brightness galaxies which is now being detected in nearby clusters.
