### Description

The Inert Doublet Model contains a neutral stable particle which is a viable dark matter candidate. I will discuss the indirect signatures of this model in gamma-rays when the dark matter mass is at the TeV scale. In particular, I will consider the interplay between the annihilation process into two photons and the internal bremsstrahlung process $DM DM \to W^+W^- \gamma$. I will show that non-perturbative effects - the so-called Sommerfeld enhancement- should be taken into account in order to satisfy the requirements from unitarity. I will illustrate all this with some benchmark points, compatible with the observed relic density and all other direct and indirect detection experiments.
