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…
First limits on the very-high energy gamma-ray afterglow emission of a fast radio burst: H.E.S.S. observations of FRB 150418
H. E. S. S. Collaboration, :, H. Abdalla +265
Aims: Following the detection of the fast radio burst FRB150418 by the SUPERB project at the Parkes radio telescope, we aim to search for very-high energy gamma-ray afterglow emiss…
Deeper H.E.S.S. observations of Vela Junior (RX J0852.04622): Morphology studies and resolved spectroscopy
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +260
Aims. We study gamma-ray emission from the shell-type supernova remnant (SNR) RX J0852.04622 to better characterize its spectral properties and its distribution over the SNR. Me…
Characterizing the gamma-ray long-term variability of PKS 2155-304 with H.E.S.S. and Fermi-LAT
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +244
Studying the temporal variability of BL Lac objects at the highest energies provides unique insights into the extreme physical processes occurring in relativistic jets and in the v…
The Single Mirror Small Sized Telescope For The Cherenkov Telescope Array
M. Heller, E. jr Schioppa, A. Porcelli +46
The Small Size Telescope with Single Mirror (SST-1M) is one of the proposed types of Small Size Telescopes (SST) for the Cherenkov Telescope Array (CTA). About 70 SST telescopes wi…
H.E.S.S. limits on line-like dark matter signatures in the 100 GeV to 2 TeV energy range close to the Galactic Centre
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +246
A search for dark matter line-like signals was performed in the vicinity of the Galactic Centre by the H.E.S.S. experiment on observational data taken in 2014. An unbinned likeliho…
The supernova remnant W49B as seen with H.E.S.S. and Fermi-LAT
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +253
The supernova remnant (SNR) W49B originated from a core-collapse supernova that occurred between one and four thousand years ago, and subsequently evolved into a mixed-morphology r…
H.E.S.S. observations of RX J1713.7-3946 with improved angular and spectral resolution; evidence for gamma-ray emission extending beyond the X-ray emitting shell
H. E. S. S. Collaboration, :, H. Abdalla +252
Supernova remnants exhibit shock fronts (shells) that can accelerate charged particles up to very high energies. In the past decade, measurements of a handful of shell-type superno…
Search for dark matter annihilations towards the inner Galactic halo from 10 years of observations with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdallah +245
The inner region of the Milky Way halo harbors a large amount of dark matter (DM). Given its proximity, it is one of the most promising targets to look for DM. We report on a searc…
A search for very high-energy flares from the microquasars GRS 1915+105, Circinus X-1, and V4641 Sgr using contemporaneous H.E.S.S. and RXTE observations
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +244
Microquasars are potential -ray emitters. Indications of transient episodes of -ray emission were recently reported in at least two systems: Cyg X-1 and Cyg X-3. The identifi…
An innovative silicon photomultiplier digitizing camera for gamma-ray astronomy
Matthieu Heller, Enrico Junior Schioppa, Alessio Porcelli +44
The single-mirror small-size telescope (SST-1M) is one of the three proposed designs for the small-size telescopes (SSTs) of the Cherenkov Telescope Array (CTA) project. The SST-1M…
Extended VHE gamma-ray emission towards SGR1806-20, LBV1806-20, and stellar cluster Cl*1806-20
H. Abdalla, A. Abramowski, F. Aharonian +241
Using the High Energy Spectroscopic System (H.E.S.S.) telescopes we have discovered a steady and extended very high-energy (VHE) gamma-ray source towards the luminous blue variable…
Acceleration of petaelectronvolt protons in the Galactic Centre
H. E. S. S. collaboration, :, A. Abramowski +229
Galactic cosmic rays reach energies of at least a few Peta-electronvolts (1 PeV = electron volts). This implies our Galaxy contains PeV accelerators (PeVatrons), bu…
