| Description | ..Massive relic galaxies. (MRGs) are local analogs of the high-redshift ..red nuggets. thought to represent progenitors of today.s early-type galaxies. MRGs, being located at low redshift, are much more accessible to detailed observational study. Analysis of a shallow AO16 Chandra ACIS-S observations of the MRG Mrk 1216 reveals an extended, luminous hot gas halo implying a massive galaxy with M200 virgul (5-10) x 10^{12} Msun. We propose an XMM-Newton observation of Mrk 1216 to map its gravitating mass profile out to a radius r_{2500}-r_{500} and obtain precise constraints (+/- 10%) on the halo concentration, total mass, and baryon fraction that will represent the first such measurements for an MRG. |

| 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. |
