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…
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…
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.…
High Energy Polarization of Blazars : Detection Prospects
Nachiketa Chakraborty, Vasiliki Pavlidou, Brian Fields
Emission from blazar jets in the ultraviolet, optical, and infrared is polarized. If these low-energy photons were inverse-Compton scattered, the upscattered high-energy photons re…
The exceptionally powerful TeV gamma-ray emitters in the Large Magellanic Cloud
H. E. S. S. Collaboration, :, A. Abramowski +226
The Large Magellanic Cloud, a satellite galaxy of the Milky Way, has been observed with the High Energy Stereoscopic System (H.E.S.S.) above an energy of 100 billion electron volts…
