A leading candidate for astrophysical dark matter (DM) is a massive particle in the range from 50 GeV/c^2
to greater than 10 TeV/c^2 and an interaction cross section on the weak scale. The self-annihilation of
such particles in astrophysical regions of high DM density can generate stable secondary particles
including very high energy gamma rays with energies up to the DM particle mass....

The H.E.S.S. experiment is an array of four identical imaging atmospheric Cherenkov telescopes in the Southern hemisphere, designed to observe very high energy gamma-rays (E > 100 GeV). These high energy gamma-rays can be used to search for annihilations of Dark Matter particles in dense environments. Dwarf galaxies dynamics shows that they are Dark Matter-dominated environments. Several...

The H.E.S.S. experiment, an array of four Imaging Atmospheric Cherenkov
Telescopes, observes the Galactic Center (GC) region in the very
high-energy (VHE, E > 100 GeV) domain since 2004. The GC is believed to
be the region with the highest Dark Matter (DM) density in our Galaxy,
thus making it one of the primary targets for VHE gamma-ray
observations, looking for signals from annihilation...

After a brief review of the theory of internal bremsstrahlung photons
in neutralino annihilation we present a detailed study of its impact
on the indirect detection of dark matter with air Cherenkov telescopes
in the halo of dwarf spheroidal galaxies using Draco as an example.
