Scientific paper

Damped Lyman alpha absorption systems (DLAs) contain most of the neutral hydrogen in the high-redshift universe and are the likely progenitors of galaxies like the Milky Way. Nonetheless, it is not yet clear whether DLAs are massive galaxies or low-mass protogalaxies, or whether they are connected with the Lyman break galaxies (LBGs) or represent a separate population. I will describe the usage of the angular and spatial cross-correlation functions to determine whether DLAs are as massive as LBGs. I will discuss the prospects for measuring these cross-correlations with ongoing observational programs.
