We propose to complete our investigation of the gas dynamics in the 150 kpcregion surrounding M87 in the Virgo cluster core. Two of our approved AO7observations were badly contaminated by flares and two were partiallycontaminated. With a complete data set, we will determine the dynamicalproperties of the gas across the surface brightness ..edge. that lies 90 kpcnorth of M87 and extends over 120 degrees in azimuth. We will derive accurategas density and temperature profiles across the edge and at all azimuths aroundM87 to derive gas pressures and gas velocities responsible for producing theedge. Assuming hydrostatic equilibrium, away from the edge, we will measure thegravitating mass profile and determine the dynamical properties of the gas in the core of M87/Virgo.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
