| Abstract | Massive relic galaxies (MRGs) are local analogs of the high-redshift rednuggets thought to represent the progenitors of todays early-type galaxies(ETGs). X-ray observation of the hot diffuse gas of MRGs is the most viablemeans to measure the global mass properties, but only a few MRGs have beenidentified as suitable for such analysis. To remedy this, we constructed asample of MRGs to map in detail their X-ray emission. We propose a snapshotsurvey of the 4 MRGs in the sample which lack X-ray data. Deep follow-upexposures with XMM-Newton and Chandra of promising targets will then be soughtto map their stellar, gas, and DM profiles to establish if high haloconcentrations are typical for MRGs and if their inner mass profiles differ from those of local ETGs. |

| 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. |
