Explorando el entorno de galaxias: grupos compactos vs. grupos difusos y galaxias de campo
Abstract
We perform a comparison of the properties of galaxies in compact groups, loose groups and in the field to deepen our understanding of the physical mechanisms acting upon galaxy evolution in different environments. On average, galaxies in compact groups are systematically smaller, more con- centrated, redder and have higher surface brightness than galaxies in the field and in loose groups. The excess of red early type galaxies in compact groups we observe may be explained in terms of: they are part of a popula- tion older than their loose group or field counterparts or/and, they have been more affected by the stripping of their bluer outskirts, resulting in redder, more compact galaxies.
