Constraining exotic high- reionization histories with Gaussian processes and the Cosmic Microwave Background
Hanyu Cheng, Ziwen Yin, Eleonora Di Valentino +2
The large-angle polarization anisotropies in the Cosmic Microwave Background (CMB) arise from Thomson scattering of CMB photons off free electrons in the post-recombination Univers…
