A very-high-energy component deep in the Gamma-ray Burst afterglow
H. Abdalla R. Adam F. Aharonian F. Ait Benkhali E. O. Anguener M. Arakawa, C. Arcaro, C. Armand +219
Gamma-ray bursts (GRBs) are brief flashes of gamma rays, considered to be the most energetic explosive phenomena in the Universe. The emission from GRBs comprises a short (typicall…
Sensitivity Improvements of Very-High-Energy Gamma-Ray Detection with the Upgraded H.E.S.S. I Cameras using Full Waveform Processing
Justus Zorn, H. E. S. S. Collaboration
The High Energy Stereoscopic System (H.E.S.S.) is an array of five imaging atmospheric Cherenkov telescopes in Namibia observing gamma-rays in the energy range from a few tens of G…
Commissioning and Performance of CHEC-S -- a compact high-energy camera for the Cherenkov Telescope Array
Jason John Watson, Justus Zorn
The Cherenkov Telescope Array (CTA) will present the next leap forward in gamma-ray astronomy, pushing beyond the present energy frontier to probe beyond 300 TeV. This capability i…
Constraints on the emission region of 3C 279 during strong flares in 2014 and 2015 through VHE gamma-ray observations with H.E.S.S
H. E. S. S. Collaboration, H. Abdalla, R. Adam +224
The flat spectrum radio quasar 3C 279 is known to exhibit pronounced variability in the high-energy (MeVGeV) -ray band, which is continuously monitored with Fer…
A photomultiplier tube test stand and on-site measurements to characterise the performance of Photonis XP3062 photomultiplier tubes at increased background light conditions and lower gain
J. Zorn, K. Daumiller, R. Engel +4
Photomultiplier tubes (PMTs) are widely used in astroparticle physics experiments to detect light flashes (e.g. fluorescence or Cherenkov light) from extensive air showers (EASs) i…
H.E.S.S. and Suzaku observations of the Vela X pulsar wind nebula
H. E. S. S. Collaboration
Pulsar Wind Nebulae (PWNe) represent the most prominent population of Galactic very-high-energy gamma-ray sources and are thought to be an efficient source of leptonic cosmic rays.…
Upper Limits on Very-High-Energy Gamma-ray Emission from Core-Collapse Supernovae Observed with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdalla +225
Young core-collapse supernovae with dense-wind progenitors may be able to accelerate cosmic-ray hadrons beyond the knee of the cosmic-ray spectrum, and this may result in measurabl…
The 2014 TeV Gamma-ray Flare of Mrk 501 Seen with H.E.S.S.: Temporal and Spectral Constraints on Lorentz Invariance Violation
H. E. S. S. Collaboration, :, H. Abdalla +232
The blazar Mrk 501 (z=0.034) was observed at very-high-energy (VHE, ~GeV) gamma-ray wavelengths during a bright flare on the night of 2014 June 23-24 (MJD 56832) with…
