| Abstract | Despite its importance for understanding clusters, there are few directmeasurements of ICM velocity structure. Hitomi measured velocities in Perseuswith its groundbreaking high resolution detector, although due to its loss wewill have to wait several years until XARM and Athena for further results. Wehave shown the EPIC-pn Cu background line can be used to calibrate its energyscale and so measure ICM velocities. We propose deep observations of theCentaurus cluster to produce a high resolution map of the velocity structure ofthe ICM, to study the Cenvirgul30-Cenvirgul45 merging system, the sloshing within thecluster and bulk motions induced by AGN feedback. We will jointly map dynamicaland thermodynamical structure across a cluster with unprecedented accuracy. |

| 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. |
