radial_profiles.convert_nfw_to_hernquist(M_200, r_200, conc)[source]#

Given M200, r200, and a concentration parameter for an NFW profile [NaFrW90], return the Hernquist ([Hern90]) mass and scale radius parameters.

Parameters:

  • M_200 (float) – The mass of the halo at r200 in Msun.

  • r_200 (float) – The radius corresponding to the overdensity of 200 times the critical density of the universe in kpc.

  • conc (float) – The concentration parameter r200/r_s for the NFW profile.

Returns:

The corresponding radial profile object.

Return type:

RadialProfile
