Calibration of the Sensitivity of Imaging Atmospheric Cherenkov Telescopes using a Reference Light Source
A. Frass, C. Koehler, G. Hermann +2
The sensitivity of an Imaging Atmospheric Cherenkov telescope is calibrated by shining, from a distant pulsed monochromatic light source, a defined photon flux onto the mirror. The…
H.E.S.S. observations of the flaring gravitationally lensed galaxy PKS 1830-211
H. E. S. S. Collaboration, :, H. Abdalla +224
PKS 1830-211 is a known macrolensed quasar located at a redshift of z=2.5. Its high-energy gamma-ray emission has been detected with the Fermi-LAT instrument and evidence for lensi…
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 millisec…
FlashCam: A fully digital camera for the Cherenkov Telescope Array
G. Pühlhofer, C. Bauer, F. Eisenkolb +21
FlashCam is a Cherenkov camera development project centered around a fully digital trigger and readout scheme with smart, digital signal processing, and a "horizontal" architecture…
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 signa…
Constraints on particle acceleration in SS433/W50 from MAGIC and H.E.S.S. observations
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +408
The large jet kinetic power and non-thermal processes occurring in the microquasar SS 433 make this source a good candidate for a very high-energy (VHE) gamma-ray emitter. Gamma-ra…
