halotools.empirical_models.halo_mass_to_halo_radius(mass, cosmology, redshift, mdef)[source] [edit on github]

Spherical overdensity radius as a function of the input mass.

Note that this function is independent of the form of the density profile.

See Halo Mass and Radius Definitions for details.

Parameters: mass: array_like Total halo mass in $$M_{\odot}/h$$; can be a number or a numpy array. cosmology : object Instance of an Astropy cosmology object. redshift: array_like Can either be a scalar, or a numpy array of the same dimension as the input mass. mdef: str String specifying the halo mass definition, e.g., ‘vir’ or ‘200m’. radius: array_like Halo radius in physical Mpc/h; has the same dimensions as input mass.
