[52.20] Lyman Alpha Emitters and Galaxy Formation Scenarios

The Large Area Lyman Alpha (LALA) survey has successfully identified the population of young Lyman-alpha emitting galaxies predicted about 35 years ago. High equivalent widths of the Lyman-alpha line in these sources suggest that they are a very young (age < 107 years), metal poor, population of stars at redshifts 4.5 and 5.7, making them very interesting objects to study in the context of galaxy formation scenarios. We have begun to do exactly this using the correlation function of LALA galaxies. While the strong correlation function indicates massive halos, the volume density of Lyman-alpha sources and the faint continuum levels indicate low-mass stellar systems. This discrepancy can be resolved by postulating multiple emitters in a single halo.
