| Description | We propose mosaic observations of the massive, early-stage, binary merging cluster Abell 401 to probe the ICM out to the virial radius with essentially full azimuthal coverage. Simulations of structure formation predict relatively large numbers of cool gas clumps in such systems, with more clumps expected along filaments. Abell 401/Abell 399 is a perfect example of such a system, with the only intercluster filament detected by Planck. We will apply the X-COP method of combining X-ray and SZ observations to accurately determine the thermodynamic profiles of the ICM, with and without clump filtering, to measure the clumping factor and fraction of non-thermal pressure support both along and away from the putative cosmic filament and compare the results with expectations from simulations. |

| 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. |
