Cosmological Evolution of Fermi Large Area Telescope Gamma-Ray Blazars Using Novel Nonparametric Methods

Multi-wavelength analyses of spectra active galactic nuclei (AGNs) provide useful information on the physical processes in accretion disk and jets black holes. This, however, is limited to bright sources may not represent population as a whole. Another approach through investigation cosmological evolution luminosity function (LF) that shows varied (luminosity density) at different wavelengths. These differences correlations between luminosities can shed light Jet-accretion connection. Most such studies use forward fitting parametric methods involve several functions many parameters. We non-parametric, non-binning developed by Efron Petrosian, Lynden-Bell, for obtaining unbiased description LF, from data truncated observational selection effects. present analysis gamma-ray LF blazars with main focus flat spectrum radio quasars (FSRQs). This requires both optical data, essential redshift measurements, joint LF. new which divides sample into two sub-samples, each its own flux limit. Fermi-LAT GAIA observations, results evolution, determine intrinsic correlation corrected well known false induced their similar dependence luminosities. also direct estimation contribution extragalactic background.
