Measuring merging comma feedback and sloshing velocities in the Ophiuchus cluster

There are few direct measurements of the intracluster medium (ICM) velocitystructure, despite its importance for understanding cluster physics. Velocitieswere measured in the Perseus cluster with the Hitomi observatory but due to itsloss we will have to wait until the next generation of Xray observatories toobtain such groundbreaking measurements. However, it has been shown that theEPICpn energy scale can be calibrated with the Cu Ka instrumental line tomeasure bulk flows of the ICM. We propose deep observations of the Ophiuchuscluster (668 ks), the secondbrightest galaxy cluster in the Xray sky, toproduce a high resolution map of the velocity structure of the ICM. Ophiuchuscluster is an excellent target to understand the heating/cooling physical processes involved. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
