An incremental version (4LAC-DR2) of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT is presented. This version is associated with the second release of the 4FGL general catalog (based on 10 years of data), where the spectral parameters, spectral energy distributions, yearly light curves, and associations have been updated for all sources. The new reported AGNs include two radio galaxies and 283 blazars. We briefly describe the properties of the new sample and… Expand
A New Sample of Gamma-Ray Emitting Jetted Active Galactic Nuclei—Preliminary Results
We are compiling a new list of gamma-ray jetted active galactic nuclei (AGN), starting from the fourth catalog of point sources of the Fermi Large Area Telescope (LAT). Our aim is to prepare a listExpand
Searching for misaligned active galactic nuclei among blazar candidates in the Fourth Fermi-LAT catalog
Abstract Radio-loud sources with blazar-like properties, but having a jet that does not directly point in the direction of the observer are among the most interesting classes of γ-ray emitters. TheseExpand
Radio Counterpart Candidates to Unassociated 4FGL-DR2 Sources
For the duration of the Fermi Gamma-Ray Space Telescope's mission, approximately one-third of the point sources detected have been noted as “unassociated,” meaning that they seem to have no knownExpand
Broadband Modeling of Low-luminosity Active Galactic Nuclei Detected in Gamma Rays
Low-luminosity active galactic nuclei are more abundant and closer to us than the luminous ones but harder to explore as they are faint. We have selected the four sources, NGC 315, NGC 4261, NGCExpand
Searching for TeV Candidates in 4LAC High-synchrotron- peaked Frequency BL Lac Objects

The next generation of TeV detectors is expected to have significantly enhanced performance. It is therefore constructive to search for new TeV candidates for observation. This paper focuses on TeVExpand
The First Gamma-Ray Emitting BL Lacertae Object at the Cosmic Dawn
One of the major challenges in studying the cosmic evolution of relativistic jets is the identification of the high-redshift ($z>3$) BL Lacertae objects, a class of jetted active galactic nucleiExpand
