AGN Triggering in the Infall Regions of Distant X-Ray Luminous Galaxy Clusters at
Figure 2
Close-up examples of the stacking process for the 9.2′ × 9.2′ cluster environments of XDCP J2215.9 − 1751 (C09) in the left panels and XDCP J2205.8 − 0159 (C12) in the right panels. Cluster positions are marked by red crosses and dashed circles, and the main elongation axis of the ICM emission is indicated by the red arrow with 2′ length in both directions from the cluster centers. The top panels show the smoothed soft-band image and the 0.35–2.4 keV detected sources (green circles) in their original orientation (North up, East to the left). The bottom panels display the rotated images and detected sources in the full 0.3–7.5 keV energy range with rotation angles that align the cluster elongation axis in the North-South direction. All panels show overlaid the soft-band X-ray surface brightness contours in cyan.
