ASD Colloquium Series
|Cosmology from the Cosmic Microwave Background: What We Know, How We Know It, and What’s Left
Suzanne Staggs (Princeton University)
In the 50+ years since its discovery, the cosmic microwave background (CMB) has yielded surprisingly detailed and precise information about the form, content and dynamics of the early universe. Recent satellite CMB data cap off a remarkably successful series of ground-based and balloon-borne experiments. In fact, those data confirm a surprisingly simple parameterization of the so-called background cosmology. High angular resolution maps, and polarization data at all angular scales, are the focus of current and next-generation instruments. I will describe what we already know about the universe from the CMB, and lay the ground for future revelations from the CMB, with special emphasis on the Atacama Cosmology Telescope, and its instrumentation and recent data.
ASD Colloquia are Tuesdays at 3:45 pm (Meet the Speaker at 3:30 pm) in Bldg 34, Room W150 unless otherwise noted.
