CLoGS (Complete Local-Volume Groups Sample)
The CLoGS project aims to be the first statistically complete survey of galaxy groups observed in the X-ray, optical and radio wavebands. Since >50% of galaxies in the local volume reside in groups, they are a key environment for studies of galaxy evolution. As the locus of much of the mass in the nearby Universe, and the environment in which the hot, X-ray emitting intergalactic medium first becomes important, groups are also fundamental to our understanding of AGN feedback and structure formation. Our main science goals include:
Determining the basic physical properties of a representative sample of groups for the first time.
Examining the temperature and density structure of the gaseous halos of groups, the ability of groups to retain gas, and the fraction of systems with central cooling cores.
Characterisation of the AGN population in groups, and examination of their impact on the intra-group gas and member galaxies.
Study of the galaxy population of groups, and the relationships between galaxies, their groups, star formation and nuclear activity.
