The Origins and Evolution of Fossil Galaxy Groups
Fossil groups (FGs) are galaxy systems with masses and X-ray haloes comparable to to those of groups and clusters of galaxies, but whose optical light is dominated by a single, large elliptical galaxy surrounded by much fainter companions. Their early assembly leaves enough time for L* galaxies to merge and makes FGs the oldest and most relaxed
