Abstract | We will use the spectro-spatial capability of XMM to map the hot gas of theentire Abell 3395-Abell 3391 region of the Horologium supercluster. Inparticular, we will: (1) measure the baryon fraction for clusters, groups, andfilamentary gas, (2) make temperature, pressure, and entropy maps to search forthe merger and infall signatures of the complex Abell 3395 3-body system, (3)construct a dynamical model of the Abell 3395-Abell 3391 filament using theX-ray measured masses combined with the galaxy kinematical parameters obtainedfrom Horologium Consortium collaborators, and (4) work with HorologiumConsortium members on a multi-waveband analysis of galaxy evolution in thecontext of large-scale structure formation. |

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. |
