Description We propose to investigate the gas dynamics in the 150 kpc region surrounding M87 with seven 20 ks pointings around the existing deep XMM-Newton observation. We will determine the dynamical properties of the gas across the surface brightness edge that lies 90 kpc north of M87 and extends 140 degrees in azimuth. We will derive accurate gas density and temperature profiles across the edge and at all azimuths around M87 and use them to derive the gas pressure distribution and the gas velocity responsible for producing the edge. Using standard hydrostatic analysis of the fields away from the edge, we will measure the gravitating mass profile. Thus, we will determine the dynamical properties of the gas to compare to observations of AGN outbursts at smaller radii.

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.
