Cosmic Microwave Background and the epoch of reionization

Description

Free electrons liberated by the reionization process scatter CMB photons and lead to additonal temperature and polarization anisotropies. Along with a large scale polarization feature there are both temperature and polarization anisotropies on arcminute scales. The signals are small, but have a lot of information about both reionization and large scale structure, especially when combined with future measurements of the 21cm signal. The currently deepest CMB experiment on arcminute scales is the South Pole Telescope; I'll report on the current status and prospects for reionization studies.
