We report on the observations of four well-localized binary black hole (BBH) mergers by the High Energy Stereoscopic System (H.E.S.S.) during the second and third observing runs of…
Leptonic non-thermal emission from supernova remnants evolving in the circumstellar magnetic field
Iurii Sushch, Robert Brose, Martin Pohl +2
The very-high-energy (VHE; E > 100 GeV) gamma-ray emission observed from a number of Supernova remnants (SNRs) indicates particle acceleration to high energies at the shock of the…
Searching for TeV gamma-ray emission from SGR\,1935+2154 during its 2020 X-ray and radio bursting phase
H. E. S. S. Collaboration, :, H. Abdalla +251
Magnetar hyperflares are the most plausible explanation for fast radio bursts (FRB) -- enigmatic powerful radio pulses with durations of several milliseconds and high brightness te…
Observation of the gamma-ray binary HESS J0632+057 with the H.E.S.S., MAGIC, and VERITAS telescopes
C. B. Adams, W. Benbow, A. Brill +409
The results of gamma-ray observations of the binary system HESS J0632+057 collected during 450 hours over 15 years, between 2004 and 2019, are presented. Data taken with the atmosp…
Modeling non-thermal emission from SN 1987A
Robert Brose, Jonathan Mackey, Sean Kelly +2
The remnant of SN 1987A is the best-studied object of its kind. The rich data-set of its thermal and non-thermal emission across the electromagnetic spectrum poses a unique testbed…
Non-thermal emission from young supernova remnants in dense circumstellar environments
Robert Brose, Jonathan Mackey, Iurii Sushch
Supernova remnants are known to accelerate cosmic rays (CRs) on account of their non-thermal emission of radio waves, X-rays, and gamma rays. However, the ability to accelerate CRs…
Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
Celine Armand, Eric Charles, Mattia di Mauro +13
Cosmological and astrophysical observations suggest that 85\% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challengi…
Morphology of supernova remnants and their halos
Robert Brose, Martin Pohl, Iurii Sushch
Supernova remnants (SNRs) are known to accelerate particles to relativistic energies, on account of their nonthermal emission. The observational progress from radio to gamma-ray ob…
VERITAS Observations of the Galactic Center Region at Multi-TeV Gamma-Ray Energies
James L Ryan
The Galactic Center region hosts a variety of powerful astronomical sources and rare astrophysical processes that emit a large flux of non-thermal radiation. We present the analysi…
VTSCat - The VERITAS Catalog of Gamma Ray Observations
Sameer Patel, Gernot Maier, Philip Kaaret
We present a catalog of results of gamma-ray observations made by VERITAS, published from 2008 to 2020. VERITAS is a ground based imaging atmospheric Cherenkov telescope observator…
The young massive stellar cluster Westerlund 1 in rays as seen with H.E.S.S
Lars Mohrmann, Andreas Specovius, Romed Rauth +2
Massive stellar clusters have recently been hypothesised as candidates for the acceleration of hadronic cosmic rays up to PeV energies. Previously, the H.E.S.S. Collaboration has r…
Science verification of the new FlashCam-based camera in the 28m telescope of H.E.S.S
Gerd Pühlhofer, Konrad Bernlöhr, Baiyang Bi +13
In October 2019 the central 28m telescope of the H.E.S.S. experiment has been upgraded with a new camera. The camera is based on the FlashCam design which has been developed in vie…
