| Description | The cluster X-ray luminosity-temperature (L-T) relationship is sensitive to cooling and feedback processes. Because L and T are used as surrogates for the cluster virial mass M in cosmological studies, understanding the L-T and the L-T-M relations-including scatter and its evolution, is critical for cluster constraints on cosmological models, as well as models of galaxy and cluster evolution. We propose to measure T and L for a representative sample of 13 low luminosity, low-T (2-2.6 keV) clusters of galaxies at moderate redshift (z=0.32 -0.37), from the ROSAT 160SD survey. We will study the L-T-M relation for 6 clusters with weak lensing masses obtained with HST. This study spans the mass range between rich clusters and groups, where feedback becomes important. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
