New hard-TeV extreme blazars detected with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +175
Extreme high-frequency peaked BL Lac objects (EHBLs) are blazars which exhibit extremely energetic synchrotron emission. They also feature non-thermal gamma-ray emission whose peak…
Bright gamma-ray flares observed in GRB131108A
Donggeun Tak, Z. Lucas Uhm, Bing Zhang
GRB 131108A is a bright long Gamma-Ray Burst (GRB) detected by the Large Area Telescope and the Gamma-ray Burst Monitor on board the Fermi Gamma-ray Space Telescope. Dedicated temp…
Performance of the INFN Camera calibration device of the first Large Size Telescope in the Cherenkov Telescope Array
Michele Palatiello, Maurizio Iori, Franca Cassol +2
On October 2018 started the commissioning of the first Large Size Telescope (LST) prototype at the Cherenkov Telescope Array (CTA) northern site at the Observatorio d…
Testing emission models on the extreme blazar 2WHSP J073326.7+515354 detected at very high energies with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +173
Extreme high-energy peaked BL Lac objects (EHBLs) are an emerging class of blazars. Their typical two-hump structured spectral energy distribution (SED) peaks at higher energies wi…
Fermi and Swift Observations of GRB 190114C: Tracing the Evolution of High-Energy Emission from Prompt to Afterglow
M. Ajello, M. Arimoto, M. Axelsson +147
We report on the observations of gamma-ray burst (GRB) 190114C by the Fermi Gamma-ray Space Telescope and the Neil Gehrels Swift Observatory. The early-time observations reveal mul…
A decade of Gamma-Ray Bursts observed by -LAT: The 2 GRB catalog
M. Axelsson, E. Bissaldi, N. Omodei +1
The Large Area Telescope (LAT) aboard the spacecraft routinely observes high-energy emission from gamma-ray bursts (GRBs). Here we present the second catalog of LAT-detecte…
Constraints on gamma-ray and neutrino emission from NGC 1068 with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +172
Starburst galaxies and star-forming active galactic nuclei (AGN) are among the candidate sources thought to contribute appreciably to the extragalactic gamma-ray and neutrino backg…
Measurement of the Extragalactic Background Light using MAGIC and Fermi-LAT gamma-ray observations of blazars up to z = 1
MAGIC collaboration, V. A. Acciari, S. Ansoldi +157
We present a measurement of the extragalactic background light (EBL) based on a joint likelihood analysis of 32 gamma-ray spectra for 12 blazars in the redshift range z = 0.03 to 0…
Fermi Large Area Telescope Fourth Source Catalog
LAT collaboration
We present the fourth Fermi Large Area Telescope catalog (4FGL) of gamma-ray sources. Based on the first eight years of science data from the Fermi Gamma-ray Space Telescope missio…
MAGIC and Fermi-LAT gamma-ray results on unassociated HAWC sources
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +336
The HAWC Collaboration released the 2HWC catalog of TeV sources, in which 19 show no association with any known high-energy (HE; E > 10 GeV) or very-high-energy (VHE; E > 300 GeV)…
