AGN Triggering in the Infall Regions of Distant X-Ray Luminous Galaxy Clusters at
Figure 1
Examples of the extraction and stacking process for the 82.2 ksec field of cluster XDCP J2215.9 − 1751 (C09) in the left panel and the 24.9 ksec observation of the system XDCP J2205.8 − 0159 (C12) in the right panel. The cluster positions and the 12′ × 12′ region around them are indicated in red. The three control fields at equivalent off-axis angles from the center position (black) are marked in blue. Green circles mark the positions of all detected soft-band X-ray point sources in the fields.
