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…
Overview of non-transient gamma-ray binaries and prospects for the Cherenkov Telescope Array
M. Chernyakova, D. Malyshev, A. Paizis +20
We simulate the spectral behaviour of the non-transient gamma-ray binaries using archival observations as a reference. With this we test the CTA capability to measure the sources'…
Observations of blazar PKS 2023-07 in flaring state with HESS and Fermi-LAT in 2016-2017 and constraints on an intrinsic cut-off
Gabriel Emery, Felix Jankowsky, Jean-Philippe Lenain +7
PKS 2023-07 is a flat spectrum radio quasar located at a redshift , farther than any source currently detected at very high energies ( GeV). At such energies, absor…
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…
Optical polarization properties of February 2010 outburst of the blazar Mrk 421
K K Singh, P J Meintjes, B van Soelen +2
In this paper, we explore the behavior of optical polarization during the multi-wavelength outburst of the blazar Mrk 421 detected in February 2010. We use optical polarization mea…
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…
