THE DISTRIBUTION OF GALAXIES IN VOIDS

We investigate the distribution of normal (faint) galaxies and blue co mpact galaxies (BCGs) in voids by analyzing their distribution as a fu nction of distance from the void centers and by employing nearest neig hbour statistics between objects of various subsamples. We find that g alaxies in voids defined by brighter galaxies tend to be concentrated close to the walls of voids in a hierarchical manner, similar to the b ehavior of brighter galaxies. The behavior of BCGs is in this respect similar to the one found for normal dwarf galaxies. The median nearest neighbour distance of BCGs from normal galaxies is approximately 0.7 h(-1) Mpc, which indicates that these galaxies are located in outlying parts of systems of galaxies defined by normal galaxies.
