Description Hot galaxy clusters at low redshift, whose structures can be mapped in detail, are rare but critical for the interpretation of lower quality data from more distant clusters. We propose to map a recently discovered, virgul9 keV, z=0.055 cluster previously hidden behind the Galactic bulge. Existing XMM data, which identified the source as a cluster, reveal merger signatures in the cluster core but, due to background issues, cannot be used to constrain the ICM out to even R2500. By extending coverage out to R500 and incorporating high resolution HI, CO, and extinction maps to account for foreground emission and absorption, we will construct kT, pressure, and entropy maps and profiles to estimate the total mass, dynamical state, and overall structure of this unique cluster.

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.
