Constraints on an annihilation signal from a core of constant dark matter density around the Milky Way center with H.E.S.S.
(American Physical Society, 2015)
An annihilation signal of dark matter is searched for from the central region of the Milky Way. Data acquired in dedicated on-off observations of the Galactic center region with H.E.S.S. are analyzed for this purpose. No ...
H.E.S.S. reveals a lack of TeV emission from the supernova remnant Puppis A
(EDP Sciences, 2015)
Context: Puppis A is an interesting ~4 kyr-old supernova remnant (SNR) that shows strong evidence of interaction between the forward shock and a molecular cloud. It has been studied in detail from radio frequencies to ...
Discovery of variable VHE γ-ray emission from the binary system 1FGL J1018.6-5856
(EDP Sciences, 2015)
Re-observations with the HESS telescope array of the very high-energy (VHE) source HESS J1018–589 A that is coincident with the Fermi-LAT γ-ray binary 1FGL J1018.6–5856 have resulted in a source detection significance of ...
The 2012 flare of PG 1553+113 seen with H.E.S.S. and Fermi-LAT
(IOP Publishing, 2015)
Very high energy (VHE, E > 100 GeV) γ-ray flaring activity of the high-frequency peaked BL Lac object PG 1553+113 has been detected by the H.E.S.S. telescopes. The flux of the source increased by a factor of 3 during the ...
H.E.S.S. detection of TeV emission from the interaction region between the supernova remnant G349.7+0.2 and a molecular cloud
(EDP Sciences, 2015)
G349.7+0.2 is a young Galactic supernova remnant (SNR) located at the distance of 11.5 kpc and observed across the entire electromagnetic spectrum from radio to high energy (HE; 0.1 GeV <E< 100 GeV) γ-rays. Radio and ...
Probing the gamma-ray emission from HESS J1834-087 using H.E.S.S. and Fermi LAT observations
(EDP Sciences, 2015)
Aims: Previous observations with the High Energy Stereoscopic System (H.E.S.S.) have revealed an extended very-high-energy (VHE; E> 100 GeV) γ-ray source, HESS J1834−087, coincident with the supernova remnant (SNR) W41. ...
VHE observations of the gamma-ray binary system LS 5039 with H.E.S.S.
(Sissa Medialab, 2015)
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 orbital
period. The X-ray and ...
Pulsations from the Vela pulsar down to 20 GeV with H.E.S.S. II
(Sissa Medialab, 2015)
The Vela pulsar (PSR J0835 − 4510) is the brightest persistent source in the high-energy γ-ray
sky. It is a relatively near, young and energetic rotation-powered pulsar. Vela was a key target for
the High Energy Stereoscopic ...
Discovery of the VHE gamma-ray source HESS J1832-093 in the vicinity of SNR G22.7-0.2
(Oxford Univ Press, 2015)
The region around the supernova remnant (SNR) W41 contains several TeV sources and has prompted the HESS Collaboration to perform deep observations of this field of view. This resulted in the discovery of the new very high ...
The high-energy γ-ray emission of AP Librae
(EDP Sciences, 2015)
The γ-ray spectrum of the low-frequency-peaked BL Lac (LBL) object AP Librae is studied, following the discovery of very-high-energy (VHE; E> 100 GeV) γ-ray emission up to the TeV range by the H.E.S.S. experiment. This ...
