  • We investigate the levels of small-scale structure in surface brightness images of the core of the X-ray bright cool-core galaxy cluster AWM 7. After subtraction of a model of the smooth cluster emission, we find a number of approximately radial surface brightness depressions which are not present in simulated images and are seen in both the Chandra and XMM–Newton data. The depressions are most strongly seen in the south of the cluster and have a magnitude of around 4 per cent in surface… CONTINUE READING
