ABSTRACT
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.

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
