Absence of Dwarf Galaxies at High Redshifts: Evidence from a Galaxy Group
2004
Astrophysical Journal
The galaxy group NGC 5044 consists of a luminous giant elliptical galaxy surrounded by a cluster of approximately 160 low luminosity and dwarf galaxies, mostly of early type. The cumulative projected radial distribution of dwarf galaxies in the NGC 5044 group, unlike distributions of more luminous galaxies in rich clusters, does not follow a projected dark matter (NFW) profile. Instead, a deficiency or absence of low luminosity galaxies is apparent in NGC 5044 within about 350 kpc, about one
