Left: 7′ image of the eROSITA events centred at the optical position of SDSSJ08 (full band 0.2–10 keV). The circle has a radius of 30″. The square shows the size of the field shown in Fig. 8. Right: G, I, and Y 60″ × 60″ HSC (PDR2) image centred at the coordinates of the SDSSJ08 associated eFEDS source. The orange cross shows the optical position of the quasar. The eROSITA contours are derived from the eFEDS image smoothed with a Gaussian kernel. Theblack dot in the lower left corner shows the eROSITA FWHM of the eROSITA PSF in survey mode (12″).
