We propose to obtain resolved X-ray temperature maps of three nearby (z < 0.1) Abell clusters; A3827, A3695 and A3911. These maps will complete the XMM and/or Chandra follow up of a luminosity complete sample of eight southern Abell clusters. Weak lensing observations are already available and Sunyaev-Zel.dovich (SZ) observations will be completed during 2002. The SZ observations are being made with the multi-frequency ACBAR instrument installed on the Viper telescope at the South Pole. With a complete multi-wavelength picture of these eight clusters, we will investigate the physical properties of the intracluster gas(i.e., density and temperature) which are paramount for the interpretation of future X-ray and Sunyaev-Zeldovich cluster surveys.

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.
