The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope -- Data Release 3
LAT collaboration, Marco Ajello, Luca Baldini +100
An incremental version of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-Large Area Telescope is presented. This version (4LAC-DR3) derives from the thir…
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…
Gamma-ray emission in radio galaxies under the VLBI scope -- II. The relationship between gamma-ray emission and parsec-scale jets in radio galaxies
R. Angioni, E. Ros, M. Kadler +22
Following our study of the radio and high-energy properties of -ray-emitting radio galaxies, here we investigate the kinematic and spectral properties of the parsec-scale jets o…
Patterns in the multi-wavelength behavior of candidate neutrino blazars
A. Franckowiak, S. Garrappa, V. Paliya +8
Motivated by the identification of the blazar TXS 0506+056 as the first promising high-energy neutrino counterpart candidate, we search for additional neutrino blazars candidates a…
Localizing the -ray emitting region in the blazar TXS 2013+370
E. Traianou, T. P. Krichbaum, B. Boccardi +9
The -ray production mechanism and its localization in blazars are still a matter of debate. The main goal of this paper is to constrain the location of the high-energy emission…
Revisiting the TeV detection prospects for radio galaxies
Roberto Angioni
Radio galaxies host relativistic jets oriented away from our line of sight, making them challenging targets for Very High Energy (VHE, E100 GeV) -ray detectors. Indeed, out o…
Gamma-ray emission in radio galaxies under the VLBI scope -- I. Parsec-scale kinematics and high-energy properties of -ray detected TANAMI radio galaxies
R. Angioni, E. Ros, M. Kadler +22
In the framework of the TANAMI multi-wavelength and VLBI monitoring, we study the evolution of the parsec-scale radio emission in radio galaxies in the southern hemisphere and thei…
The large gamma-ray flare of the FSRQ PKS 0346-27
R. Angioni, R. Nesci, J. D. Finke +2
In this paper, we characterize the first -ray flaring episode of the FSRQ PKS 0346-27 (z=0.991), as revealed by Fermi-LAT monitoring data, and the concurrent multi-wavelength va…
The TeV-emitting radio galaxy 3C 264. VLBI kinematics and SED modeling
B. Boccardi, G. Migliori, P. Grandi +5
In March 2018, Mukherjee (2018) reported the detection by VERITAS of very-high-energy emission (VHE; > 100 GeV) from 3C 264. This is the sixth, and second most distant, radio galax…
The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope
LAT collaboration
The fourth catalog of active galactic nuclei (AGNs) detected by the Fermi Gamma-ray Space Telescope Large Area Telescope (4LAC) between 2008 August 4 and 2016 August 2 contains 286…
Detection of a gamma-ray flare from the high-redshift blazar DA 193
Vaidehi S. Paliya, M. Ajello, R. Ojha +10
High-redshift () blazars are the most powerful members of the blazar family. Yet, only a handful of them have both X-ray and -ray detection, thereby making it difficult to…
Multi-messenger observations of a flaring blazar coincident with high-energy neutrino IceCube-170922A
The IceCube, Fermi-LAT, MAGIC +13
Individual astrophysical sources previously detected in neutrinos are limited to the Sun and the supernova 1987A, whereas the origins of the diffuse flux of high-energy cosmic neut…
Extended X-ray emission in PKS 1718649
T. Beuchert, A. Rodríguez-Ardila, V. A. Moss +15
PKS 1718649 is one of the closest and most comprehensively studied candidates of a young active galactic nucleus (AGN) that is still embedded in its optical host galaxy. The com…
TANAMI: Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry - II. Additional Sources
C. Müller, M. Kadler, R. Ojha +31
TANAMI is a multiwavelength program monitoring active galactic nuclei (AGN) south of -30deg declination including high-resolution Very Long Baseline Interferometry (VLBI) imaging,…
Radio Galaxies with the Cherenkov Telescope Array
R. Angioni, P. Grandi, E. Torresi +2
Misaligned AGN (MAGNs), i.e., radio-loud AGNs with the jet not pointing directly towards us, represent a new class of GeV emitters revealed by the Fermi space telescope. Although t…
VLBI studies of TANAMI radio galaxies
Roberto Angioni, Florian Rösch, Eduardo Ros +4
Radio galaxies are relatively faint at -ray energies, where they make up only 1-2% of all AGN detected by Fermi-LAT. However, they offer a unique perspective to study the intrin…
