halomod.concentration.Bullock01Power

class halomod.concentration.Bullock01Power(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)

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

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

Notes

The form of the concentration is

..math:: c_{rm vir} = a/(1+z)^cbig(frac{m}{m_s}big)^b

where a,b,c,ms are model parameters.

Parameters

• a (float) – Default value is a=9.0, b=-0.13 and c=1.0.

• b (float) – Default value is a=9.0, b=-0.13 and c=1.0.

• c (float) – Default value is a=9.0, b=-0.13 and c=1.0.

• ms (float) – Default value is None, where it’s set to be the non-linear mass at z.
