Title Revealing the WHIM and Accretion Physics between Two Nearby Galaxy Clusters

Author Dr Ka-Wah Wong
Description We propose to search for X-ray emission from the warm-hot intergalactic medium (WHIM) between a nearby (z=0.06) double galaxy cluster system Abell 2625-2626 which is located in the 300virgulMpc long Perseus--Pegasus filament and is orient- ated almost along the line of sight. Our previous observation of the more mass-ive cluster Abell 2626 has indicated that it is preferentially accreting mater-ial from this filament. Physical properties of the WHIM such as density and temperature will be constrained. We will also search for subclusters-clumps along the filament and merging signatures of the less massive cluster Abell 2625. The proposed observation will reveal the dynamical accretion processes of clusters and groups along this large-scale filamentary structure in detail.

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.
