Colloquium

The polarized microwave background: ACTPol and beyond

Measurements of the Cosmic Microwave Background radiation have taught us a great deal about the origins and content of the universe, but there is still more information to be extracted, teaching us about the energetic moments in the early universe, about neutrino physics, and the later-time expansion of the Universe. I will show new results from the Atacama Cosmology Telescope Polarimeter in northern Chile, an experiment measuring the polarization of the CMB. I will then talk about the future: plans for new measurements from the ground from the Simons Observatory and the CMB-S4 experiment, and from space with the PIXIE satellite.

Followed by wine and cheese in Pupin 301.
