Title: Probing the faint end of the redshift 6 Quasars luminosity function

Abstract: Observations of high redshift (z>5) quasars provide strong constraints on the state of the intergalactic medium in the early Universe, on the growth of black holes, and in turn on models of galaxy formation and evolution. Currently known high redshift quasars probe mostly the bright end of the luminosity function. Here, we select 16 high redshift quasars candidates from Medium Deep Pan-STARRS1 imaging. These candidates, if confirmed, will help to put constraints on the number density of faint quasars at z 6, and the source of reionization of the Universe. We propose a pilot survey to get deep J band imaging for selected candidates, in order to confirm that they are high redshift quasars.
