"A CMB Perspective of the Epoch of Reionization"

The cosmic microwave background (CMB) is revolutionizing our understanding of the Universe. The CMB is the strongest single piece of evidence that we live in a geometrically flat Universe, dominated by non-baryonic cold dark matter and dark energy. Many outstanding questions remain around this basic framework: Did inflation occur, and what physics was responsible for it? What are the neutrino masses? What drove the reionization of neutral Hydrogen in the early Universe? Remarkably the CMB can shed light on all of these questions. I will present the latest results from the South Pole Telescope (SPT), which recently finished a millimeter-wave survey of 2500 square degrees of sky with unprecedented sensitivity and angular resolution. I will highlight the latest measurements of the kinetic Sunyaev-Zel'dovich (SZ) effect, which is produced by the patchwork pattern of ionized and neutral bubbles created during cosmic reionization. The shape of the kinetic SZ power spectrum depends on the typical bubble sizes, while the amplitude depends on the duration of reionization. I will discuss the implications of these measurements for our understanding of how reionization occurred. I will conclude with an update on two experiments that are exploring the next frontier in CMB science: using gravitational lensing to map the matter distribution in the Universe.
