- SphericalOverdensity.r_to_m(r, 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 mass corresponding to r for this mass definition
- Parameters
r (float or array_like) – The radius to convert to mass. Units should be compatible with
halo_density()
.
Notes
Computed as \(\frac{4\pi r^3}{3} \rho_{\rm halo}\).
