IDECAMB: an implementation of interacting dark energy cosmology in CAMB

Understand

Interacting dark energy (IDE) scenario is a natural and important extension to the standard $\Lambda$CDM cosmology.

• We develop a full numerical routine, called IDECAMB, as a patch to the public Einstein-Boltzmann solver CAMB, to solve the background and perturbation equations of the IDE models.
• The IDECAMB solver provides a unified interface for the widely studied IDE models by employing a parametrization model with five free functions.
• By configuring these five functions, one can easily map the coupled quintessence (CQ) and coupled fluid (CF) models into the parametrization.
