The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 2
B. Lott, D. Gasparrini, S. Ciprini
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…
Optical spectroscopic observations of low-energy counterparts of Fermi-LAT gamma-ray sources
H. A. Peña-Herazo, R. A. Amaya-Almazán, F. Massaro +15
A significant fraction of all -ray sources detected by the Large Area Telescope aboard the \fer\ satellite is still lacking a low-energy counterpart. In addition, there is still…
On the physical association of Fermi-LAT blazars with their low-energy counterparts
Raniere de Menezes, Raffaele D'Abrusco, Francesco Massaro +2
Associating gamma-ray sources to their low-energy counterparts is one of the major challenges of modern gamma-ray astronomy. In the context of the Fourth Fermi Large Area Telescope…
Optical spectroscopic observations of gamma-ray blazar candidates. X. Results from the 2018--2019 SOAR and OAN-SPM observations of blazar candidates of uncertain type
Raniere de Menezes, Raul A. Amaya-Almazán, Ezequiel J. Marchesini +14
The fourth Fermi Large Area Telescope Source Catalog (4FGL) lists over 5000 gamma-ray sources with statistical significance above 4. About 23% of the sources listed in this cata…
Gamma-ray observations of low-luminosity active galactic nuclei
Raniere de Menezes, Rodrigo Nemmen, Justin D. Finke +2
The majority of the activity around nearby (z ~ 0) supermassive black holes is found in low-luminosity active galactic nuclei (LLAGN), the most of them being classified as low ioni…
