Abstract
AbstractWe discuss an analysis of the redshift evolutions and distributions of the gamma-ray luminosity and photon spectral index of flat spectrum radio quasar (FSRQ) type blazars. We utilize data from the Fermi Gamma-ray Space Telescope, with redshfits as determined from optical spectroscopy by Shaw et al. We find that FSRQs have evolved significantly in luminosity but negligibly in photon index, and contribute in toto roughly 20% of the total gamma-ray output of the Universe.
