Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS
THE MASS--TEMPERATURE RELATIONSHIP OF GALAXY CLUSTERS
ABSTRACT
Theoretical arguments and simulations suggest that the total mass of a galaxy cluster is tightly correlated to its x-ray temperature and that the lower end of the M-T relationship is sensitive to non-gravitational effects, such as energy injection by galactic winds. We have investigated the M-T relationship for a variety of mass estimation techniques. We propose ASCA observations of a sample of six low mass clusters to obtain accurate x-ray temperatures. This will nearly the double the number of clusters with accurate virial masses and ASCA temperatures in the region 2--3 keV and will allow a determination of the scaling of viral mass and temperature over the full range of rich cluster masses.
