| Abstract | Within the framework of an extensive radio observational campaign aimed tosearch for radio halos and relics in galaxy clusters in the redshift range0.2-0.4 at 610 MHz, we propose to observe one cluster of our sample which isexceptional in the radio band and therefore extremely promising for testing themerging paradigm. RXCJ1314.4-2515 is the unique case known to date of galaxycluster hosting both a radio halo and a double relic. Our goal is to reconstructthe detailed dynamics of this cluster and to test the physical properties of theICM related to the relics 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. |
