We assess a model of late cosmic reionization in which the ionizing background radiation arises entirely from highredshift quasars and other active galactic nuclei (AGNs). The low optical depth to Thomson scattering reported by the Planck Collaboration pushes the redshift of instantaneous reionization down to z = 8.8-1.4+1.7and greatly reduces the need for significant Lyman-continuum… CONTINUE READING
