Comparison between the X-ray, the ICL and the ICGCs of Perseus. The background image is the H_E image with the light from NGC 1272 modelled and subtracted. Cyan contours show the X-ray emission of the intracluster medium observed by Chandra (Sanders et al. 2016), adaptively smoothed to reach a S /N = 15, and further smoothed with a Gaussian kernel of σ = 12″. Orange contours show the distribution of GCs, not including those from NGC 1272, binned and smoothed with a Gaussian kernel on scales of 40″.
