AGN observations with a less than 100 GeV threshold using H.E.S.S. II
Dmitry Zaborov, Carlo Romoli, Andrew M. Taylor +3
The recent addition of the 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity towards low energies. The lowest energy threshold is obtained…
VHE observations of the gamma-ray binary system LS 5039 with H.E.S.S
C. Mariaud, P. Bordas, F. Aharonian +5
LS 5039 is a gamma-ray binary system observed in a broad energy range, from radio to TeV energies. The binary system exhibits both flux and spectral modulation as a function of its…
Rapid variability at very high energies in Mrk 501
Nachiketa Chakraborty, Gabriele Cologna, Max Anton Kastendieck +5
A major flaring state of the BL Lac object Mrk 501 was observed by the High Energy Stereoscopic System (H.E.S.S.) in June, 2014. Flux levels higher than one Crab unit were recorded…
Long term lightcurve of the BL Lac object 1ES 0229+200 at TeV energies
Gabriele Cologna, Mahmoud Mohamed, Stefan J. Wagner +3
The high-frequency peaked BL Lac object 1ES 0229+200 (z = 0.14) was first detected in very high energy (VHE, E > 100 GeV) -rays by the H.E.S.S. (High Energy Stereoscopic System)…
Spectral characteristics of Mrk 501 during the 2012 and 2014 flaring states
Gabriele Cologna, Nachiketa Chakraborty, Mahmoud Mohamed +6
Observations at Very High Energies (VHE, E > 100 GeV) of the BL Lac object Mrk 501 taken with the High Energy Stereoscopic System (H.E.S.S.) in four distinct periods between 2004 a…
H.E.S.S. observations of PSR B1259-63 during its 2014 periastron passage
C. Romoli, P. Bordas, C. Mariaud +8
An extended observation campaign of the gamma-ray binary system PSR B125963 has been conducted with the H.E.S.S. (High Energy Stereoscopic System) II 5-telescope array during th…
