wcosmo.wcosmo.comoving_distance(z, H0, Om0, w0=-1, method='pade')[source]#

Compute the comoving distance using an analytic integral of the Pade approximation.

\[d_{C} = d_{H} \int_{0}^{z} \frac{dz'}{E(z'; \Omega_{m,0}, w_0)}\]

Parameters:

z: array_like: Redshift
H0: array_like: The Hubble constant in km/s/Mpc
Om0: array_like: The matter density fraction
w0: array_like: The (constant) equation of state parameter for dark energy

Returns:

comoving_distance: array_like: The comoving distance in Mpc
