Scientific paper
We propose to continue our successful XMM-Newton program to measure the properties of the intragroup medium in a sample of galaxy groups at moderate redshifts. Previously, we have observed groups at z0.2. Here, we propose to extend our study to higher redshifts by observing four X-ray bright groups in the redshift range z0.31 to z0.45. We will combine the new XMM observations with our existing HST imaging and groundbased spectroscopy to: 1) measure the evolution of metallicity of the intragroup medium from z0 to nearly z0.5; 2) determine if the correlations between X-ray properties and morphological content hold at moderate redshifts; and 3) determine the masses and baryon fractions of intermediate redshift groups.
