| Abstract | Shock waves are one of the most important phenomena to understand the growth ofgalaxy clusters and large-scale structures. In particular for accretion shocks,due to faint emission at the expected region, no study has yet been performed onan individual object. Here we propose deep 228 ksec XMM-Newton and a Chandrasnapshot (25 ksec) observations of the bridge connecting the massive galaxyclusters Abell 399-Abell 401 to identify and characterize the nature of a shockonto the bridge, which is potentially an accretion shock. To provide solidconfirmation and a better understanding of the possible shock structure, theproposed observations together with our multi-wavelength (radio, SZ) data aim todetermine the temperature and surface brightness profiles of the shock candidate. |

| 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. |
