New information encoded in CMB photons

A new window into the growth and evolution of large-scale structure has opened up with the recent measurements kinetic Sunyaev-Zel’dovich (SZ) effect. I will review these recent detections and the current limits that kinetic SZ observations are placing on reioinization models. I will show how we can constrain the important baryonic process that govern galaxy formation through SZ measurements. Additionally, I will describe the prospects for future CMB experiments to constrain fundamental physics from kinetic SZ observations and how to mitigate the modeling uncertainties associated with the baryonic processes that will limit these constraints.
