XMM-Newton observations of the ..double. clusters A98 and A1750 will addressthree goals: 1) detect early merger signatures in the subclusters and determinethe cluster dynamics using X-ray data and galaxy spectroscopy, 2)search forintercluster gas (WHIM) between subclusters, and 3) for A98, study theinteraction of the double-lobed radio source 4C+20.04 with the ICM and determinethe AGN power responsible for this outburst. We propose two pointings for A98and one for A1750, which combined with the existing observations will image alllarge subclusters in each system, as well as the intervening regions betweensubclusters.

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.
