We propose to map the distribution and variation in density and temperature of the intracluster medium in and between the members of the A3528 complex:A3528-north, A3528-south, A3530, A3532. This allows us to study how on-going mergers affect the dynamical parameters of these clusters andthe physical characteristics of the galaxy population.The proposed XMM observations will complement our extensive studies of theA3528 complex in the Shapley Supercluster that we are carrying on in the optical and radio wavebands.

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.
