Gamma-ray blazar spectra with H.E.S.S. II mono analysis: the case of PKS 2155-304 and PG 1553+113
D. Zaborov, A. M. Taylor, D. A. Sanchez +2
The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity to lower energies, providing new opportunities for studies of Active Ga…
Gamma-ray blazar spectra with H.E.S.S. II mono analysis: the case of PKS 2155-304 and PG 1553+113
H. E. S. S. Collaboration, :, H. Abdalla +332
The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity to lower energies. The lowest energy threshold is obtained using monosc…
The second catalog of flaring gamma-ray sources from the Fermi All-sky Variability Analysis
S. Abdollahi, M. Ackermann, M. Ajello +124
We present the second catalog of flaring gamma-ray sources (2FAV) detected with the Fermi All-sky Variability Analysis (FAVA), a tool that blindly searches for transients over the…
The Chandra Survey of Extragalactic Sources in the 3CR Catalog: X-ray Emission from Nuclei, Jets, and Hotspots in the Chandra Archival Observations
F. Massaro, D. E. Harris, E. Liuzzo +8
As part of our program to build a complete radio and X-ray database of all the 3CR extragalactic radio sources, we present an analysis of 93 sources for which Chandra archival data…
The awakening of the gamma-ray narrow-Line Seyfert 1 galaxy PKS 1502+036
F. D'Ammando, M. Orienti, J. Finke +7
After a long low-activity period, a gamma-ray flare from the narrow-line Seyfert 1 PKS 1502+036 (z=0.4089) was detected by the Large Area Telescope (LAT) on board Fermi in 2015. On…
A Panchromatic View of Relativistic Jets in Narrow-Line Seyfert 1 Galaxies
F. D'Ammando, M. Orienti, J. Finke +3
The discovery by the Large Area Telescope on board Fermi of variable gamma-ray emission from radio-loud narrow-line Seyfert 1 (NLSy1) galaxies revealed the presence of a possible t…
