| Abstract | In A0-6 we proposed to observe the galaxy cluster RXCJ1314.4--2515 which wasapproved in priority A. Unfortunately the observation is affected by strongflares for 69% of the time. We propose to re-observe it to compensate for thetime loss. RXCJ1314.4--2515 was selected from an extensive radio observationalcampaign aimed to search for radio halos and relics in galaxy clusters in theredshift range 0.2$div$0.4 at 610 MHz. RXCJ1314.4--2515 is exceptional as it isthe unique case known to date of a cluster hosting both a radio halo and adouble relic. The detailed study of the dynamics of this cluster will help us totest the merging paradigm and the physical properties of the ICM related to therelics and halo formation. |

| 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. |
