VizieR Online Data Catalog: Gamma-ray emitting jetted AGN (Foschini+, 2022)
Abstract
From the 4FGL-DR2 gamma-ray source catalogue (2020ApJS..247...33A, Cat. J/ApJS/247/33) we select extragalactic or unclassified counterparts (excluding starburst and normal galaxies), and outside the Galactic plane (|b|>10°). For 2980 gamma-ray sources we searched for redshift measurements and optical spectra in the literature. For those without spectroscopic redshifts we extract photometric redshifts from 13 different references and provide their average value. For 59 4FGL counterparts we provide revised counterpart positions which differ from those of the 4FGL-DR2 catalogue by 0.3 to 215 arcsec.
