Gamma-ray flaring activity from the gravitationally lensed blazar PKS 1830-211 observed by Fermi LAT
The Fermi LAT Collaboration, A. A. Abdo, M. Ackermann +126
The Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope routinely detects the highly dust-absorbed, reddened, and MeV-peaked flat spectrum radio quasar PKS 1830…
The spectrum of isotropic diffuse gamma-ray emission between 100 MeV and 820 GeV
The Fermi LAT collaboration, M. Ackermann, M. Ajello +142
The γ-ray sky can be decomposed into individually detected sources, diffuse emission attributed to the interactions of Galactic cosmic rays with gas and radiation fields, and a res…
Radio-Gamma-ray connection and spectral evolution in 4C +49.22 (S4 1150+49): the Fermi, Swift and Planck view
S. Cutini, S. Ciprini, M. Orienti +23
The Large Area Telescope on board the Fermi Gamma-ray Space Telescope detected a strong gamma-ray flare on 2011 May 15 from a source identified as 4C 49.22, a flat spectrum radio q…
First broadband characterization and redshift determination of the VHE blazar MAGIC J2001+439
MAGIC Collaboration, J. Aleksić, S. Ansoldi +167
We aim to characterize the broadband emission from 2FGL J2001.1+4352, which has been associated with the unknown-redshift blazar MG4 J200112+4352. Based on its gamma-ray spectral p…
Exploring the multiband emission of TXS 0536+145: the most distant gamma-ray flaring blazar
M. Orienti, F. D'Ammando, M. Giroletti +4
We report results of a multiband monitoring campaign of the flat spectrum radio quasar TXS 0536+145 at redshift 2.69. This source was detected during a very high gamma-ray activity…
Probing the very-high-energy gamma-ray spectral curvature in the blazar PG 1553+113 with the MAGIC telescopes
MAGIC Collaboration, J. Aleksić, S. Ansoldi +152
PG 1553+113 is a very-high-energy (VHE, ) -ray emitter classified as a BL Lac object. Its redshift is constrained by intergalactic absorption lines in the r…
