Description Bent, double-lobed radio sources associated with active galactic nuclei (AGN) are frequently found in clusters of galaxies. The hosts of these radio sources are typically giant elliptical galaxies and the radio lobes are bent through interaction with the hot gas of the intracluster medium. Our Spitzer infrared observations of the fields surrounding 646 bent radio sources have revealed approximately 200 new, distant clusters. These objects comprise the high-z Clusters Occupied by Bent Radio AGN (COBRA) survey. Here, we propose EPIC observations of 7 COBRA clusters which show significant galaxy number overdensities in infrared and optical images and that have redshift estimates z > 1.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
