Quasar UV luminosity function evolution up to z = 8

Abstract

We study the redshift evolution of the quasar (QSO) UV luminosity function (LF) for 0.5 < z 6 QSOs detectable by ongoing and future near-infrared surveys (as EUCLID and Wide-Field Infrared Survey Telescope), and (ii) number counts for a single radio-recombination line observation with Square Kilometre Array-MID (FoV = 0.49 deg2) as a function of the Hna flux density, at 0 < z < 8. These surveys (even at z < 6) will be fundamental to better constrain the role of QSOs as reionization sources.
