Abstract
The High Energy Stereoscopic System (H.E.S.S.) is an array of four imaging air-Cherenkov telescopes located in the Khomas Highlands of Namibia (23° 16' 18" S, 16° 30' 1" E, 1800m above sea level). The stereoscopic technique gives H.E.S.S. good angular resolution (<0.1°) and excellent background rejection (>99%). These properties coupled with the low energy threshold (~100 GeV)of the detector allows the detection of a 1% Crab flux source in ~25 hours of observation. H.E.S.S. can therefore perform searches for VHE gamma-ray emission from astrophysical objects, such as AGN, with unprecedented sensitivity. The detections by H.E.S.S. of VHE gamma rays from the blazars PKS 2155-304, Mkn 421 and PKS 2005-489 are reported here.
