Description
Indirect searches for dark matter annihilation or decay products in the cosmic-ray
spectrum are plagued by the question of how to disentangle a dark matter signal from
the omnipresent astrophysical background. One of the practically background-free
`smoking gun' signatures for dark matter would be the observation of a sharp cutoff
in the gamma-ray energy spectrum. Such a feature is generically produced in many dark
matter models by internal Bremsstrahlung, and it can be treated in a similar manner
as the traditionally looked-for gamma-ray lines. In this talk, we will discuss
prospects for seeing such features with present and future gamma-ray telescopes. We
will concentrate on Air Cherenkov Telescopes and comment on the Fermi LAT.
