radial_profiles.vikhlinin_density_profile#
- radial_profiles.vikhlinin_density_profile(rho_0, r_c, r_s, alpha, beta, epsilon, gamma=None)[source]#
A modified beta-model density profile for galaxy clusters from [ViKrF06].
- Parameters:
rho_0 (
float) – The scale density in Msun/kpc**3.r_c (
float) – The core radius in kpc.r_s (
float) – The scale radius in kpc.alpha (
float) – The inner logarithmic slope parameter.beta (
float) – The middle logarithmic slope parameter.epsilon (
float) – The outer logarithmic slope parameter.gamma (
float) – This parameter controls the width of the outer transition. If None, it will be gamma = 3 by default.
- Returns:
The corresponding radial profile object.
- Return type:
