| Abstract | We propose a 3$times$50 ks XMM-Newton mosaic observation of the ram pressurestripped tail of NGC 4472. Our goal is to measure the width, length, and massprofile of the tail of stripped gas to constrain the infall history.Simultaneously, the morphology, density, and temperature of the gas in the tailwill provide unique constraints on the transport processes of the Virgo ICM atthe virial radius. We compare the observation with ram pressure strippingsimulations tailored for NGC 4472. The simulations explore the observableeffects of the ICM properties like effective viscosity or magnetic fieldstructure in the dynamical context of NGC 4472. |

| 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. |
