An optical overview of blazars with LAMOST I: Hunting changing-look blazars and new redshift estimates
Harold A. Peña-Herazo, Francesco Massaro, Minfeng Gu +6
The extragalactic -rays sky observed by Fermi-Large Area Telescope (LAT) is dominated by blazars. In the fourth release of the Fermi-LAT Point Source Catalog (4FGL), are sources…
Peering Into the Extended X-ray Emission on Megaparsec Scale in 3C 187
A. Paggi, F. Massaro, H. A. Pena-Herazo +7
Context. The diffuse X-ray emission surrounding radio galaxies is generally interpreted either as due to inverse Compton scattering of non-thermal radio-emitting electrons on the C…
Extended X-ray emission around FR II radio galaxies: hotspots, lobes and galaxy clusters
Ana Jimenez-Gallardo, Francesco Massaro, Alessandro Paggi +20
We present a systematic analysis of the extended X-ray emission discovered around 35 FR II radio galaxies from the revised Third Cambridge catalog (3CR) Chandra Snapshot Survey wit…
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…
Fermi Large Area Telescope Fourth Source Catalog Data Release 2
J. Ballet, T. H. Burnett, S. W. Digel +1
We present an incremental version (4FGL-DR2, for Data Release 2) of the fourth Fermi-LAT catalog of gamma-ray sources. Based on the first ten years of science data in the energy ra…
