TL;DR
This paper presents the third catalog of AGNs detected by the Fermi LAT, expanding the number of known sources and analyzing their properties based on four years of gamma-ray data.
Contribution
It introduces the 3LAC, a comprehensive catalog of 1591 AGNs detected with the Fermi LAT, with detailed analysis of their gamma-ray properties and classifications.
Findings
71% increase in AGN sources compared to previous catalog
Detailed correlations between gamma-ray flux, spectral indices, and redshift
Identification of variability patterns across different AGN classes
Abstract
The third catalog of active galactic nuclei (AGNs) detected by the Fermi Large Area Telescope (3LAC) is presented. It is based on the third catalog (3FGL,\cite{3FGL}) of sources detected with a test statistic greater than 25, using the first 4 years of data. The 3LAC includes 1591 AGNs located at high () Galactic latitudes (with 28 duplicate associations, thus corresponding to 1563 gamma-ray sources among 2192 sources in the 3FGL catalog), providing more sources with respect to the 2FGL. Various properties, such as gamma-ray fluxes and photon power law spectral indices, redshifts, gamma-ray luminosities, variability, and their correlations are presented and discussed for the different blazar and non-blazar classes.
