Search for Very-high-energy gamma-ray emission from Galactic globular clusters with H.E.S.S
P. Eger, C. van Eldik
Globular clusters (GCs) are established emitters of high-energy (HE, 100 MeV<E<100 GeV) γ-ray radiation which could originate from the cumulative emission of the numerous milliseco…
H.E.S.S. discovery of VHE gamma-rays from the quasar PKS 1510-089
H. E. S. S. Collaboration, A. Abramowski, F. Acero +204
The quasar PKS 1510-089 (z=0.361) was observed with the H.E.S.S. array of imaging atmospheric Cherenkov telescopes during high states in the optical and GeV bands, to search for ve…
Discovery of TeV gamma-ray emission from PKS 0447-439 and derivation of an upper limit on its redshift
H. E. S. S. Collaboration, :, A. Abramowski +204
Very high-energy gamma-ray emission from PKS 0447-439 was detected with the H.E.S.S. Cherenkov telescope array in December 2009. This blazar is one of the brightest extragalactic o…
H.E.S.S. Observations of the Binary System PSR B1259-63/LS 2883 around the 2010/2011 Periastron Passage
H. E. S. S. Collaboration, :, A. Abramowski +203
Aim. In this paper we present very high energy (VHE; E>100 GeV) data from the γ-ray binary system PSR B1259-63/LS 2883 taken around its periastron passage (15th of December 2010) w…
Search for Very-high-energy γ-ray emission from Galactic globular clusters with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +203
Globular clusters (GCs) are established emitters of high-energy (HE, 100 MeV<E<100 GeV) γ-ray radiation which could originate from the cumulative emission of the numerous milliseco…
Search for photon line-like signatures from Dark Matter annihilations with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +201
Gamma-ray line signatures can be expected in the very-high-energy (VHE; E_γ> 100 GeV) domain due to self-annihilation or decay of dark matter (DM) particles in space. Such a signal…
