Centre for Particle Theory Colloquia: Cosmology from the Cosmic Microwave Background
6 March 2012 16:00 in CLC202
I will describe the status of current Cosmic Microwave Background observations. I will then focus on recent results from the Atacama Cosmology Telescope, which has mapped the microwave sky to arcminute scales. I will present results from ACT, as well as the South Pole Telescope, on the angular power spectrum of the Cosmic Microwave Background fluctuations, measuring primordial acoustic oscillations well into the Silk damping tail. I will also describe the extraction of a gravitational lensing signal from these observations, and the detection of galaxy clusters via the Sunyaev-Zel'dovich effect. I will describe the implications of these various measurements for cosmology, and discuss prospects for the Planck satellite, and upcoming ground-based experiments.
