Modeling of the Radio Emission from the Vela Supernova Remnant
Iurii Sushch, Bohdan Hnatyk
Supernova remnants (SNRs) are widely considered to be sites of Galactic cosmic ray (CR) acceleration. Vela is one of the nearest Galactic composite SNRs to Earth accompanied by the…
Long-term TeV and X-ray Observations of the Gamma-ray Binary HESS J0632+057
VERITAS Collaboration, E. Aliu, S. Archambault +297
HESS J0632+057 is the only gamma-ray binary known so far whose position in the sky allows observations with ground-based observatories both in the northern and southern hemispheres…
Constraints on axionlike particles with H.E.S.S. from the irregularity of the PKS 2155-304 energy spectrum
H. E. S. S. Collaboration, A. Abramowski, F. Acero +211
Axionlike particles (ALPs) are hypothetical light (sub-eV) bosons predicted in some extensions of the Standard Model of particle physics. In astrophysical environments comprising h…
H.E.S.S. Observations of the Crab during its March 2013 GeV Gamma-Ray Flare
H. E. S. S. Collaboration, A. Abramowski, F. Aharonian +217
Context. On March 4, 2013, the Fermi-LAT and AGILE reported a flare from the direction of the Crab Nebula in which the high-energy (HE; E > 100 MeV) flux was six times above its qu…
HESS J1818-154, a new composite supernova remnant discovered in TeV gamma rays and X-rays
H. E. S. S. Collaboration, A. Abramowski, F. Aharonian +217
Composite supernova remnants (SNRs) constitute a small subclass of the remnants of massive stellar explosions where non-thermal radiation is observed from both the expanding shell-…
Discovery of very high energy gamma-ray emission from the BL Lac object PKS 0301-243 with H.E.S.S
H. E. S. S. Collaboration, A. Abramowski, F. Acero +211
The active galactic nucleus PKS 0301-243 (z=0.266) is a high-synchrotron-peaked BL Lac object that is detected at high energies (HE, 100 MeV < E < 100 GeV) by Fermi/LAT. This paper…
