Abstract | We propose to observe an intermediate redshift gravitational lensing cluster ofgalaxies with XMM. The galaxy cluster CL0500-24 at redshift z = 0.33 isoptically very rich and even produces a straight gravitationally lensed arcof a background galaxy. The X-ray morphology and luminosity obtained with aROSAT HRI observation indicate that the cluster consists of two physicallyseparated subclumps. The derived X-ray mass estimate/baryon fraction arelow/high and have large error bars. XMM observations will help to determine thedynamical state of this cluster, its temperature and gas mass fraction. |

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. |
