Abstract:
We study the distribution of gas pressure and entropy in eight groups
of galaxies belonging to the ROSAT All-Sky Survey/Center for
Astrophysics Loose Systems (RASSCALS, Cat. J/ApJ/534/114). We use
archival and proprietary XMM-Newton observations, supplementing the
X-ray data with redshifts derived from the literature; we also list
125 new redshifts measured with the Gemini North telescope.
