radial_profiles.ad07_density_profile(T0, t, a, alpha, f, n=4, mu=0.6, omega_b=0.048, omega_dm=0.262)[source]#

Pseudo-polytropic gas density profile from [AsDi08].

Parameters:

  • T0 (float) – (keV) The core temperature of the gas distribution.

  • t (float) – (Dimensionless) value representing the degree of cooling in the cluster core.

  • a (float) – (kpc) Scale length of both the temperature and density profiles.

  • alpha (float) – (dimensionless) Ratio of a_c/a, a_c is the cooling radius.

  • f (float) – (dimensionless) The gas fraction.

  • n (int, optional) – (dimensionless) the polytropic index. Default is 4.

  • mu (float, optional) – (dimensionless) the mean molecular mass of the gas. Default is 0.6

  • omega_b (float, optional) – (dimensionless) the cosmic baryon fraction parameter. Default is 0.048.

  • omega_dm (float, optional) – (dimensionless) the cosmic dark matter fraction parameter. Default is 0.262

Returns:

The corresponding radial profile.

Return type:

radial_profiles.RadialProfile
