Panel a: bolometric luminosity as a function of redshift for the total WISSH sample, compared to SDSS QSOs from Shen et al. (2011) and COSMOS QSOs from Lusso et al. (2012). Cyan stars indicate WISSH QSOs with (sub-)millimetre observations. Panel b: bolometric luminosity vs. black hole mass. We include WISSH QSOs with Hβ-based MBH from Vietri et al. (2018) and luminous SDSS QSOs from Shen (2016). Lines correspond to LBol/LEdd = 1 (dashed), LBol/LEdd = 0.5 (solid), and LBol/LEdd = 0.1 (dotted).
