Fig. 2


Full-band (0.5–7 keV) cutouts of the 18 detected sources (the first 16 images from Chandra, the following five from XMM and the last one from Swift). The XMM images are obtained summing data from the three detectors (pn, MOS1, MOS2). Red circles represent our extraction regions (2′′ and 10′′ radius for Chandra and XMM/Swift, respectively). The grid separations are 5′′ and 20′′ for Chandra and XMM/Swift QSOs, respectively. Each panel spans 20′′× 20′′ and 100′′× 100′′ on the sky for Chandra and XMM/Swift QSOs, respectively. For clarity the XMM/Swift images have been smoothed with a three pixel radius Gaussian function. The XMM cutout of J1148+5251 is shown in the 0.2–12 keV band.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
