halomod.concentration.Bullock01

class halomod.concentration.Bullock01(cosmo: hmf.cosmology.cosmo.Cosmology = <hmf.cosmology.cosmo.Cosmology object>, filter0: Optional[hmf.density_field.filters.Filter] = None, growth: Optional[hmf.cosmology.growth_factor.GrowthFactor] = None, delta_c: float = 1.686, profile: Optional[halomod.profiles.Profile] = None, mdef: Optional[hmf.halos.mass_definitions.MassDefinition] = None, **model_parameters)

Concentration-Mass relation of Bullock et al.(2001) [1].

See documentation for Bias for information on input parameters. This model has two model parameters.

Notes

The form of the concentration is

\[c_{\rm vir} = K a/a_c = K (1+z_c)/(1+z)\]

The detailed description of the model can be found in [1].

Parameters

• F (float) – Default value is F=0.01 and K=0.34

• K (float) – Default value is F=0.01 and K=0.34
