We will use a 50 ks EPIC observation to probe galaxy-IGM-radio jet interactionsin the dumbbell galaxies NGC4782(3C278) and NGC4783. We will constructtemperature, density, and pressure maps to delineate the large scale structureof the group IGM and properties of the hot gas in and around the interactinggalaxies and radio jets to (1) constrain the dynamical motion of NGC4782 andNGC4783 relative to the IGM, (2) determine the mass, temperature, and density ofthe hot ISM in each galaxy and in the IGM, (3) study gas-stripping processesthrough the properties of the galaxy wakes and inter-connecting bridge, and (4)constrain models of radio jet interactions, (e.g. through jet bending anddeceleration, plume and X-ray knot formation) with the IGM and galaxy ISM.

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.
