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.
Held Tuesdays at 4:15 pm, in the William R. Hewlett Teaching Center, room 200 (see map). Refreshments in the lobby of Varian Physics at 4:00 pm.
