Median surface brightness profiles and 16–84th percentile of the X-ray emission (rest-frame 0.5 − 2.0 keV) of the IGrM in groups in the halo mass bin M500 = 1013 − 1013.5M. The sample is divided into bins of the rescaled accretion rate of the central BH in the host halo (left panel) and hot gas fraction (right panel). We plot a dotted line corresponding to 0.15R500 to separate the central from the external contribution given in Fig. 2.
