Centre for Particle Theory Colloquia: Cosmology from the Cosmic Microwave Background

Presented by Joanna Dunkley, Oxford

6 March 2012 16:00 in CLC 202

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.
