Description There are few direct measurements of the intracluster medium (ICM) velocity structure, despite its importance for understanding cluster physics. Velocities were measured in the Perseus cluster with the Hitomi observatory but due to its loss we will have to wait until the next generation of X-ray observatories to obtain such groundbreaking measurements. However, it has been shown that the EPIC-pn energy scale can be calibrated with the Cu Ka instrumental line to measure bulk flows of the ICM. We propose deep observations of the Ophiuchus cluster (668 ks), the second-brightest galaxy cluster in the X-ray sky, to produce a high resolution map of the velocity structure of the ICM. Ophiuchus cluster is an excellent target to understand the heating-cooling physical processes involved.

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.
