class flowpm.cosmology.Cosmology(Omega_c, Omega_b, h, n_s, sigma8, Omega_k, w0, wa)

Bases: object

Cosmology object, stores primary and derived cosmological parameters.

Parameters

• Omega_c – float representing the cold dark matter density fraction.

• Omega_b – float representing the baryonic matter density fraction.

• h – float representing Hubble constant divided by 100 km/s/Mpc; unitless.

• n_s – float representing the primordial scalar perturbation spectral index.

• sigma8 – float representing the variance of matter density perturbations at an 8 Mpc/h scale.

• Omega_k – float representing the curvature density fraction.

• w0 – float representing the first order term of dark energy equation.

• wa – float representing the second order term of dark energy equation of state.
