Caption: Figure 2.

X-ray detection of BBQSORS with XMM-Newton. The left panel presents the EPIC/pn image in the 0.4–7.2 keV (rest frame ∼1–20 keV) band, detected at a significance of 3.42σ. The green circle indicates the source region with a radius of 20″. The right panel shows the EPIC/pn spectrum folded with the energy response (blue squares) and the best-fitting model (black curve), consisting of source and background components. Residuals between the data and the model are shown in the bottom panel.
