|Gas Dynamics Around M87
|Dr William Forman
|We propose to complete our investigation of the gas dynamics in the 150 kpc region surrounding M87 in the Virgo cluster core. Two of our approved AO7 observations were badly contaminated by flares and two were partially contaminated. With a complete data set, we will determine the dynamical properties of the gas across the surface brightness ..edge. that lies 90 kpc north of M87 and extends over 120 degrees in azimuth. We will derive accurate gas density and temperature profiles across the edge and at all azimuths around M87 to derive gas pressures and gas velocities responsible for producing the edge. Assuming hydrostatic equilibrium, away from the edge, we will measure the gravitating mass profile and determine the dynamical properties of the gas in the core of M87-Virgo.

|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.
