The link between optical lines and X-ray sloshing in two unusual clusters
Abstract
The inter-relation between ICM gas cooling, optical line emission and the Brightest Cluster Galaxy (BCG) in the cores of clusters is known to be close from 20 years of intense multifrequency observations. However, we don't currently understand the mechanisms for this cooling and how quickly any cold gas reservoir is created. We propose to observe two unusual systems that have extended optical emission line gas offset from the BCG revealed from recent MUSE observations. One of these systems, A2533, appears to be a long, thin filament that runs through the centre of the galaxy. If these two systems are comparable to the three much less striking ones we currently know, then we expect the X-ray peak to coincide with the optical line emission and to find evidence for sloshing of the ICM.
