The star formation histories of fossil group galaxies
arXiv:0909.5066 · doi:10.1017/S1743921310003042
Abstract
A comparison is carried out among the star formation histories of early-type galaxies (ETG) in fossil groups, clusters and low density environments. Although they show similar evolutionary histories, a significant fraction of the fossils are younger than their counterparts, suggesting that fossils can be precursors of the isolated ETGs.
