It provides a versatile tool for computing dark matter indirect detection signals in any new model with a stable weakly interacting particle.

Findings

Calculates gamma ray, positron, and antiproton fluxes from dark matter annihilation.

Includes a flexible charged particle propagation module.

Supports any new model with a stable weakly interacting particle.

Abstract

We present a new module of micrOMEGAs devoted to the computation of indirect signals from dark matter annihilation in any new model with a stable weakly interacting particle. The code provides the mass spectrum, cross-sections, relic density and exotic fluxes of gamma rays, positrons and antiprotons. The propagation of charged particles in the Galactic halo is handled with a new module that allows to easily modify the propagation parameters.
