We propose to observe the cluster of galaxies A 1835 to verify the capabilityof the RGS to analyse spatially resolved extended sources. A 1835 is anideal target for this since it has a FWHM of only 0.8 arcmin, allowinga high spectral resolution with the RGS and also an almost completecoverage of the cooling flow region within the cross-dispersion widthof the detector. In particular we will study the temperature andabundance distribution of the cooling flow region. The EPIC observationswill supplement this for the outer regions of the cluster, wherewe will study the abundance and temperature gradients as well asinvestigate the existence of non-thermal components.

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.
