Search for Pulsed VHE Gamma-Ray Emission from Young Pulsars with H.E.S.S
The HESS Collaboration, F. Aharonian
We present the results of a search for pulsed very-high-energy (VHE) gamma-ray emission from young pulsars using data taken with the H.E.S.S. imaging atmospheric Cherenkov telescop…
Mrk 421, Mrk 501, and 1ES 1426+428 at 100 GeV with the CELESTE Cherenkov Telescope
D. A. Smith, E. Brion, R. Britto +18
We have measured the gamma-ray fluxes of the blazars Mrk 421 and Mrk 501 in the energy range between 50 and 350 GeV (1.2 to 8.3 x 10^25 Hz). The detector, called CELESTE, used firs…
A search for very high energy gamma-ray emission from the starburst galaxy NGC 253 with H.E.S.S
F. Aharonian et al.
We present the result of 28 hours of observations of the nearby starburst galaxy NGC 253 with the H.E.S.S. detector in 2003. We find no evidence for very high energy gamma-ray emis…
Observations of Selected AGN with H.E.S.S
F. Aharonian et al.
A sample of selected active galactic nuclei (AGN) was observed in 2003 and 2004 with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging atmospheric-Cherenkov teles…
Upper limits to the SN1006 multi-TeV gamma-ray flux from H.E.S.S. observations
F. Aharonian
Observations of the shell-type supernova remnant SN1006 have been carried out with the H.E.S.S. system of Cherenkov telescopes during 2003 (18.2h with two operating telescopes) and…
New constraints on space-time Planck scale fluctuations from established high energy astronomy observations
R. Le Gallou
The space-time metric is widely believed to be subject to stochastic fluctuations induced by quantum gravity at the Planck scale. This work is based on two different phenomenologic…
