The Sculptor and Carina dwarf spheroidal galaxies were observed with the H.E.S.S. Cherenkov telescope array between January 2008 and December 2009. The data sets consist of a total of 11.8h and 14.8h of high quality data, respectively. No gamma-ray signal was detected at the nominal positions of these galaxies above 220GeV and 320GeV, respectively. Upper limits on the gamma-ray fluxes at 95% CL assuming...
Observations of the Sagittarius dwarf spheroidal (Sgr dSph) galaxy were carried out with the HESS array of four imaging air Cherenkov telescopes in June 2006. A total of 11h of high quality data are available after data selection. There is no evidence for a very high energy γ-ray signal above the energy threshold at the target position. A 95% CL flux limit of 3.6×10-12cm-2s-1 above 250GeV has been...
