The XMM-Newton EPIC image (100″ × 100″) of J0439+1634, combined from the pn, MOS1, and MOS2 images, in the 0.2–0.5 keV (left), 0.5–2 keV (middle), and 2–10 keV (right) X-ray bands. The central crosses represent the optical coordinates of this quasar (i.e., J043947.08+163415.7, Fan et al. 2019). The quasar is detected in the 0.5–2 keV (rest-frame 3.8–15 keV) and 2–10 keV (rest-frame 15–75 keV) bands, but not in the 0.2–0.5 keV band (rest-frame 1.5–3.8 keV).
