Description We propose to observe an intermediate redshift gravitational lensing cluster of galaxies with XMM. The galaxy cluster CL0500-24 at redshift z = 0.33 is optically very rich and even produces a "straight" gravitationally lensed arc of a background galaxy. The X-ray morphology and luminosity obtained with a ROSAT HRI observation indicate that the cluster consists of two physically separated subclumps. The derived X-ray mass estimate-baryon fraction are low-high and have large error bars. XMM observations will help to determine the dynamical state of this cluster, its temperature and gas mass fraction.

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.
