MassDefinition.m_to_r(m, z=0, cosmo=FlatLambdaCDM(name="Planck15", H0=67.7 km / (Mpc s), Om0=0.307, Tcmb0=2.725 K, Neff=3.05, m_nu=[0.   0.   0.06] eV, Ob0=0.0486))

Return the radius corresponding to m for this mass definition

Parameters

m (float or array_like) – The mass to convert to radius. Should be in the same units (modulo volume) as halo_density().

Notes

Computed as \(\left(\frac{3m}{4\pi \rho_{\rm halo}\right)\).
