Code package for calculating modified cosmic ionization and thermal histories with dark matter and other exotic energy injections

We present a new public python package, darkhistory, for computing the effects of dark matter annihilation and decay on the temperature and ionization history of the early universe. darkhistory simultaneously solves for the evolution of the free electron fraction and gas temperature, and for the coo...
