RoboPol: First season rotations of optical polarization plane in blazars
D. Blinov, V. Pavlidou, I. Papadakis +25
We present first results on polarization swings in optical emission of blazars obtained by RoboPol, a monitoring program of an unbiased sample of gamma-ray bright blazars specially…
Discovery of variable VHE gamma-ray emission from the binary system 1FGL J1018.6-5856
H. E. S. S. Collaboration, :, A. Abramowski +230
Re-observations with the H.E.S.S. telescope array of the very-high-energy (VHE) source HESS J1018-589 A coincident with the Fermi-LAT -ray binary 1FGL J1018.6-5856 have resulted…
Constraints on an Annihilation Signal from a Core of Constant Dark Matter Density around the Milky Way Center with H.E.S.S
HESS Collaboration, A. Abramowski, F. Aharonian +223
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.…
The 2012 flare of PG 1553+113 seen with H.E.S.S. and Fermi-LAT
A. Abramowski, F. Aharonian, F. Ait Benkhali +224
Very high energy (VHE, 100 GeV) -ray flaring activity of the high-frequency peaked BL Lac object \pg\ has been detected by the \hess\ telescopes. The flux of the source incr…
