Abstract (from CDS):

From near-infrared spectroscopic measurements of the Mg II emission line doublet, we estimate the black hole (BH) mass of the quasar, SMSS J215728.21-360215.1, as being (3.4 ± 0.6) x 1010 M☉ and refine the redshift of the quasar to be z = 4.692. SMSS J2157 is the most luminous known quasar, with a 3000 Å luminosity of (4.7 ± 0.5) x 1047 erg s–1 and an estimated bolometric luminosity of 1.6 x 1048 erg s–1, yet its Eddington ratio is only ∼0.4. Thus, the high luminosity of this quasar is a consequence of its extremely large BH - one of the most massive BHs at z > 4.
