Forward emulation to speed up cosmological parameter estimation,

A pseudo-spectral solver for ultra-light dark matter dynamics.

ModeCode provides a numerical solution of the perturbation equations and resulting spectrum for an arbitrary single field inflationary potential. Interfaced with CAMB and CosmoMC, to implement Bayesian parameter estimation for inflation.
