PrimaryFlux#

class gammapy.astro.darkmatter.PrimaryFlux(mDM, channel)[source]#

Bases: gammapy.modeling.models.spectral.TemplateNDSpectralModel

DM-annihilation gamma-ray spectra.

Based on the precomputed models by Cirelli et al. (2016). All available annihilation channels can be found there. The dark matter mass will be set to the nearest available value. The spectra will be available as TemplateNDSpectralModel for a chosen dark matter mass and annihilation channel. Using a TemplateNDSpectralModel allows the interpolation between different dark matter masses.

Parameters

mDMQuantity: Dark matter particle mass as rest mass energy.
channel: str: Annihilation channel. List available channels with allowed_channels.
