| Description | We propose to complete our investigation of the massive group centered on the cD galaxy NGC4839, which is falling into the Coma cluster. The completed observations will allow the physics and dynamics of this merger to be studied in unprecedented detail. Our 112 ks (80 ks plus 40% overhead) XMM-Newton observation was badly flared. To complete our program, we request an additional 58 ks (which includes 40% overhead). With a complete data set, we will determine the nature of the shock/sheath region at the interface between the Coma ICM and the group gas, investigate the newly identified (120x75 kpc) cocoon surrounding NGC4839, and study the 400 kpc ram pressure stripped tail behind NGC4839 to determine the importance of mixing of cluster gas with stripped group gas. |

| 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. |
