darkhistory.physics.f_std

darkhistory.physics.f_std(mDM, rs, inj_particle=None, inj_type=None, struct=False, channel=None)

energy deposition fraction into channel c, f_c(z), as a function of dark matter mass and redshift.

Parameters:

mDM : float

Dark matter mass

inj_particle : string

Injected particle, either set to ‘phot’ for photons, or ‘elec’ for electrons.

inj_type : string

Type of energy injection, either ‘swave’ or ‘decay

struct : bool

If True, include structure formation, if False assume no structure formation. Default is False. This option makes no difference for decays.
