Description
Gamma rays from the annihilation of dark matter particles in the Galactic
halo provide a particularly promising means of indirectly detecting dark
matter. Here, we demonstrate that pronounced spectral features near the
kinematic cutoff at the dark matter particles' mass, which is a generic
prediction for most models, can significantly improve the sensitivity of
gamma-ray telescopes to dark matter signals. We derive projected limits on such
features (including the traditionally looked-for line signals) and show that
these can be very efficient in constraining the nature of dark matter.
