| Description | We propose XMM-Newton observations of Abell 3653, the rich cluster with one of the largest known cD galaxy peculiar velocities. Previous Chandra observations of A2670 and A2107, two other clusters with large cD motions, have shown that they are merging systems. Our recent Chandra observation of Abell 3653 shows a cold front (CF) associated with the high velocity cD galaxy. We will use the stagnation condition to determine the speed of the CF, which will be compared to he optical z of the cD. Recent surveys show that rapidly moving cDs are not terribly rare. We will study the origin of these motions, and the implications for the origin of cD galaxies, and the dynamics of cluster cores. |

| 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. |
