X-ray bright groups and their galaxies.
HELSDON S.F. and PONMAN T.J.
Abstract (from CDS):
We also use the optical and X-ray data to investigate whether early- or late-type galaxies are primarily responsible for pre-heating in groups. Using three different methods, we conclude that spiral galaxies appear to play a comparable role to early types in the pre-heating of the intragroup medium. This tends to favour models in which the pre-heating arises primarily from galaxy winds rather than active galactic nuclei and implies that spirals have played a significant role in the metal enrichment of the intragroup medium.
