Extended Data Fig. 6: Optical luminosity vs. αox correlation.
From: A dusty compact object bridging galaxies and quasars at cosmic dawn
The black and blue squares denote SDSS quasars18,80,169 at z ~ 0–4 and blue quasars76,81,82 at z > 5 respectively, taken from the literature. The arrows present the upper limits. The black line represents the best-fit relation based on 1544 quasars taken from the literature76. The gray shaded region denotes the 68th percentile derivation, evaluated by propagating the 1σ uncertainties of the parameters that define the best-fit relation. The αox upper limit of GNz7q (99% confidence level) is estimated after the extinction correction and deviated from the best-fit relation by more than 5σ.
