Title Re-observation of Hydra A SE


DOI 10.5270/esa-99hqnlx
Author Dr Dominique Eckert
Description Galaxy cluster outskirts are the regions where structure formation occurs through the accretion of smaller structures along large-scale filaments. Recently, it has been claimed both from observations and numerical simulations that an important fraction of the infalling material should be in the form of dense clumps. Unfortunately, the observation of the Hydra A SE field, which is crucial for the completion of our program for the study of gas clumping accepted in AO-11, was badly affected by soft proton flares. This field is located along a filament, and already allowed us to unveil the presence of accreting substructures. Therefore, we ask for a re-observation of this crucial field with XMM, to allow the completion of our AO-11 program.

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.
