Characterising the VHE diffuse emission in the central 200 parsecs of our Galaxy with H.E.S.S.
(EDP Sciences, 2018)The diffuse very high-energy (VHE; >100 GeV) γ-ray emission observed in the central 200 pc of the Milky Way by H.E.S.S. was found to follow dense matter distribution in the central molecular zone (CMZ) up to a longitudinal ... -
Cosmic-ray acceleration and escape from post-adiabatic supernova remnants
(EDP Sciences, 2020)Context. Supernova remnants are known to accelerate cosmic rays on account of their nonthermal emission of radio waves, X-rays, and gamma rays. Although there are many models for the acceleration of cosmic rays in supernova ... -
H.E.S.S. observations of the Crab during its March 2013 GeV gamma-ray flare
(EDP Sciences, 2014)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 quiescent level. Simultaneous observations ... -
HESS J1741-302: a hidden accelerator in the Galactic plane
(EDP Sciences, 2018)The H.E.S.S. Collaboration has discovered a new very high energy (VHE, E > 0.1 TeV) γ-ray source, HESS J1741−302, located in the Galactic plane. Despite several attempts to constrain its nature, no plausible counterpart ... -
Prospects for Cherenkov Telescope Array observations of the young supernova remnant RX J1713.7−3946
(AAS, 2017)We perform simulations for future Cherenkov Telescope Array (CTA) observations of RX J1713.7−3946, a young supernova remnant (SNR) and one of the brightest sources ever discovered in very high energy (VHE) gamma rays. ... -
Systematic search for very-high-energy gamma-ray emission from bow shocks of runaway stars
(EDP Sciences, 2018)Context. Runaway stars form bow shocks by ploughing through the interstellar medium at supersonic speeds and are promising sources of non-thermal emission of photons. One of these objects has been found to emit non-thermal ...
