| Description | Stacking of SZ signals (Y) by stellar mass produces a significant signal, which has been used to infer the halo gas mass of galaxies. Interpreting the stacked signal assumes the Y distribution (at fixed M*) is narrow, symmetric, and for a uniform sample of objects. These conditions are violated when stacking in stellar mass bins, so one must understand the distribution of Y as a function of galaxy environment (M*, gal/M*,tot). This cannot be obtained from the weak individual SZ signals, but can be inferred from X-ray observations. We propose to complete our X-ray studies of 15 nearby galaxies that were previously used in a stack of SZ signals. We will measure the distribution of Y _X (X-ray analog of SZ) to quantify the dependence of halo gas mass on galaxy environment. |

| 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. |
