Title: The Faint End of the Quasar Luminosity Function at z=5

Abstract: High redshift quasars probe the rapid growth of supermassive black holes in the early Universe. One of the primary observables is the quasar luminosity function (QLF), which traces the lifecycle of black hole accretion. The QLF constrains models of quasar activity and fueling, whether driven predominantly by mergers of galaxies or cold flows from the IGM. We propose to target faint (i 24) quasars in the CFHTLS-W4 field with GMOS-N, reaching well into the faint end of the quasar luminosity function at redshifts where it is poorly constrained from existing data. This data will provide strong constraints on models of black hole fueling at the earliest epochs currently explored by quasar surveys.
