Probing the extent of the non-thermal emission from the Vela X region at TeV energies with H.E.S.S.
(EDP Sciences, 2012)
Context. Vela X is a region of extended radio emission in the western part of the Vela constellation: one of the nearest pulsar wind nebulae, and associated with the energetic Vela pulsar (PSR B0833-45). Extended ...
HESS J1640-465: an exceptionally luminous TeV γ-ray supernova remnant
(Oxford Univ Press, 2014)
The results of follow-up observations of the TeV γ-ray source HESS J1640−465 from 2004 to 2011 with the High Energy Stereoscopic System (HESS) are reported in this work. The spectrum is well described by an exponential ...
TeV γ-ray observations of the young synchrotron-dominated SNRs G1.9+0.3 and G330.2+1.0 with H.E.S.S.
(Oxford Univ Press, 2014)
The nonthermal
nature of the Xray
emission from the shelltype
supernova remnants (SNRs)
G1.9+0.3 and G330.2+1.0 is an indication of intense particle acceleration in the shock fronts
of both objects. This suggests that ...
Long-term monitoring of PKS2155-304 with ATOM and H.E.S.S.: investigation of optical/y-ray correlations in different spectral states
(EDP Sciences, 2014)
In this paper we report on the analysis of all the available optical and very high-energy
y-ray (>200 GeV) data for the BL Lac object PKS 2155-304,
collected simultaneously with the ATOM and H.E.S.S. telescopes from ...
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 ...
The y-ray spectrum of the core of Centaurus A as observed with H.E.S.S. and Fermi-LAT
(EDP Sciences, 2018)
Centaurus A (Cen A) is the nearest radio galaxy discovered as a very-high-energy (VHE; 100 GeV–100 TeV) γ-ray source by the High Energy Stereoscopic System (H.E.S.S.). It is a faint VHE γ-ray emitter, though its VHE flux ...
Characterizing the γ-ray long-term variability of PKS 2155-304 with H.E.S.S. and Fermi-LAT
(EDP Sciences, 2017)
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 vicinity of super-massive black holes. To ...
H.E.S.S. discovery of very high energy γ-ray emission from PKS 0625−354
(Oxford Univ Press, 2018)
PKS 0625−354 (z = 0.055) was observed with the four High Energy Stereoscopic System (H.E.S.S.) telescopes in 2012 during 5.5 h. The source was detected above an energy threshold of 200 GeV at a significance level of 6.1σ. ...
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 ...
