We propose a deep observation of the cluster Abell 400, which is host to thespectacular double twin-jet radio source 3C 75. The radio jets of each sourceshow a number of bends which are common to both sources and are reflective ofenvironmental conditions. Our initial short Chandra exposure shows the elongatedcluster emission is clumpy; there is a hot X-ray region south of the AGN and acool region to the north. Our previous AO-4 XMM observations (for the HIFLUGCSproject) were lost due to flares. We will study the ICM density, temperature andpressure in the region of the radio source. These observations will allow us toexamine the mechanism responsible for deflecting the twin tails: Is it due tothe merger, density gradients, or inhomogeneities?

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.
