Strange Hosts of Blue Compact Galaxies

Abstract

Luminous Blue Compact Galaxies (BCGs) have low metallicities, high gas consumption rates and are frequently involved in mergers. These are properties characteristic of young galaxies in the hierarchical formation scenario. Local BCGs can therefore be used as a complement to high redshift studies provided that the evolution of BCGs can be understood in more detail and be applied to early galaxy formation. Although much is known about the central starburst, few studies discuss the relation between the starburst and the progenitor, or the “host galaxy” of the starburst. Here we report of an effort to derive information about the host from the colours of the faint halo.
