Whitford Lecture
WMAP and Beyond
Date: Thursday, October 22nd
Time: 2:00 pm - 3:30 pm
Place: 3425 Sterling Hall
Speaker: Dr. David Spergel, Princeton University
Abstract: CMB experiments have made an accurate full-sky measurement of the microwave background temperature and polarization fluctuations. These measurements probe both the physics of the very early universe and the basic properties of the universe today. These measurements rigorously test our standard cosmological model and provide an accurate determination of basic cosmological parameters (the curvature of the universe,its matter density and composition).

I will review the results from WMAP and describe recent results from the Atacama Cosmology Telescope (ACT) and look forward to the upcoming results from Planck. ACT small scale measurements not only probe early universe physics but offer a new tool for studying the evolution of clusters and large-scale structure.
