Spectra of newly discovered eRASS quasars (left panel) and eRASS:4 (0.2–8 keV) postage stamps (right panel). The cutouts are 2′×2′ in size and are centred on the optical position of the quasars. The spectrum of J202040−621509 shows prominent broad absorption features. The continuum appears strongly absorbed over the entire spectral range bluewards of Lyman α. It appears in the eROSITA images as two distinct sources. This morphology is further investigated in Section 4.3.1 with a Chandra follow-up pointing. There, we argue that the eRASS source is related to the quasar (Fig. 11). The morphology J020916−562650 is more compact.
