Abstract:
The coincidence problem is a fundamental barrier to making significant progress in modern cosmology. A model with multiple phases of acceleration would potentially alleviate our coincidence problem. We use MCMC to make an exhaustive study in search of the possibility to disguise, in current CMB data, a second Dark Energy phase, of arbitrary duration (e-foldings), at any time between the BBN epochs and today.
