T. D. Lee Inst. Seminar 3-2017


Speaker: Prof. Arthur Kosowsky (University of Pittsburgh)
Title: Current and Future Science from the Cosmic Microwave Background
Time: 1:30 pm - 2:30 pm, Mar.1 (Wednesday) 
Place: Meeting Room 402 of T. D. Lee Inst., 4th floor of T. D. Lee Library

Host:  Prof. Pengjie Zhang

Abstract: Over the past decade, increasingly precise maps of the cosmic microwave background intensity and polarization have established the standard model of cosmology to high precision.  Now, the background radiation is being used as a way to probe the evolution of the universe since the time of last scattering. I will highlight a number of results from the Atacama Cosmology Telescope collaboration, including motions of galaxy clusters via the kinematic unyaev-Zeldovich effect, quasar feedback via the thermal Sunyaev-Zeldovich Effect, and gravitational lensing. Future goals include inflationary tensor perturbations, distinguishing modified gravity from dark energy, and measurement of neutrino masses.
