wcosmo.taylor#

Utilities based on the Taylor expansion of the functions of the form \(\frac{(1 + z)^k}{E(z)}\) for flat wCDM cosmology. These functions and their integral are estimated using the Pade approximation.

flat_wcdm_pade_coefficients([w0, zpower, xp])

Compute the Pade coefficients as described in arXiv:1111.6396.

flat_wcdm_taylor_expansion(w0[, zpower, xp])

Taylor coefficients expansion of \(E(z)\) as as a function of \(w_0\) and an arbitrary power \(k\) of \(1 + z\).

indefinite_integral_pade(z, Om0[, w0, zpower])

Compute the Pade approximation to \((1+z)^k / E(z)\) as described in arXiv:1111.6396.
