GDR vs. dust mass. The horizontal black line represents GDR = 100. Red circles are the z > 7 quasars presented in this work with M_H2 upper limits. Green circles are for J1007 from Feruglio et al. (2023), J1120 from Venemans et al. (2017a), and J1342 from Novak et al. (2019). Gray circles are the 6 ≲ z < 7 quasars from Table C.1, while blue dots are for quasars at lower redshifts from Bischetti et al. (2021), Decarli et al. (2022), and Salvestrini et al. (in prep.). Local Seyfert galaxies are shown as red diamonds.
