Dust mass and molecular gas mass vs. redshift. Upper panel:M_d vs. redshift. Red circles are the z > 7 quasars presented in this work. Green circles are for J1120 from Venemans et al. (2017a), J1007 from Feruglio et al. (2023), and J1342 from Novak et al. (2019). Gray circles are the 5 < z < 7 quasars from Venemans et al. (2017b), Izumi et al. (2021), Decarli et al. (2022), and Tripodi et al. (2024a), while blue dots are for quasars at intermediate redshifts (1 < z < 5) from Bischetti et al. (2021) and Salvestrini et al. (in prep.). Lower panel:M_H2 vs. redshift. Data are color-coded as in the upper panel. We also include the quasars at intermediate redshifts (1 < z < 5) from Bertola et al. (2024).
