Applied Physics/Physics Colloquium: ACT and the CMB in Polarization

Topic: 
ACT and the CMB in Polarization
Tuesday, October 14, 2014 - 4:15pm to 5:15pm
Venue: 
Hewlett 200
Speaker: 
Lyman Page (Princeton University)
Abstract / Description: 

We have a well-established standard model of cosmology. After a review of its foundations from a CMB perspective, we discuss new tests of the model with a focus on what we can learn with polarization. In addition to the search for primordial gravitational waves, the CMB polarization can be used to assess the sum of neutrino masses and the dark energy. In light of this we present recent results from the Atacama Cosmology Telescope and discuss future plans. The CMB is still a goldmine for measuring the cosmos.  We have an enormous amount left to learn from it.
