HEP - ASTRO SEMINAR | CMB Lensing: Fundamental Physics from Maps of the Invisible

Wednesday, January 27, 2016

340 West Hall

Note unusual day and time! <br>

Dark matter not only underlies the formation of all visible structures, but its distribution in the universe contains a wealth of information about fundamental physics. Measurements of gravitational lensing in the cosmic microwave background (CMB) allow the projection of this distribution to be directly seen. In my talk, I will describe the rapid advance of CMB lensing measurements from first detections to precision cosmology. I will explain how upcoming CMB lensing measurements will allow us to determine the mass scale of neutrinos and probe the properties of inflation and the early universe.
