halomod.concentration.Ludlow16¶

class halomod.concentration.Ludlow16(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)[source]¶

Analytical Concentration-Mass relation of Ludlow et al.(2016) [1].

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

Notes

Note

The form of the concentration is described by eq(6) and eq(7) in [1].

Parameters

f (float) – Default value is f=0.02 and C=650
C (float) – Default value is f=0.02 and C=650
