Abstract We propose to investigate the gas dynamics in the 150 kpc region surrounding M87with seven 20 ks pointings around the existing deep XMM-Newton observation. Wewill determine the dynamical properties of the gas across the surface brightnessedge that lies 90 kpc north of M87 and extends 140 degrees in azimuth. We willderive accurate gas density and temperature profiles across the edge and at allazimuths around M87 and use them to derive the gas pressure distribution and thegas velocity responsible for producing the edge. Using standard hydrostaticanalysis of the fields away from the edge, we will measure the gravitating massprofile. Thus, we will determine the dynamical properties of the gas to compareto observations of AGN outbursts at smaller radii.

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.
