We present a numerically efficient and accurate implementation of the Passaglia-Hu effective fluid approximation for ultralight axions (ULAs) within the Boltzmann code CAMB. This method is specifically designed to evolve the axion field accurately ac... Read More about Fast and accurate implementation of the effective fluid approximation for ultralight axions.
