CAA-Seminar 12：Fundamental Physics from the Planck Satellite, revealing Simplicity & Complexity (J. Richard Bond, Oct.11, 2013)

Title: Fundamental Physics from the Planck Satellite, revealing Simplicity & Complexity

Speaker: Professor J. Richard Bond, CITA

Time and place: 14:00-15:00,Oct.11（Friday）, 2013, CAA Lecture Hall,jianchuan Road 955

Abstract:

I will discuss our first Planck constraints on early and late universe inflation, including on the shape of the primordial power spectrum, on popular inflaton potentials, and on patterns of primordial non-Gaussianity. The dramatic large scale anomalies persistent through COBE, WMAP and Planck could have an early universe explanation, as subdominant intermittent non-Gaussianity from modulated entropy generation at the end of inflation. At the other end, allowed Dark Energy trajectories remain compatible with no late-inflaton kinetic energy density.

Professor J.Richard Bond (Dick Bond) is a leading cosmologist worldwide. He has made many pioneering and profound contributions in areas such as cosmic microwave background，the large scale structure of the universe, dark matter and dark energy, and physics of the early universe. He is a university professor at University of Toronto, director of Canadian Institute for Advanced Research Cosmology and Gravity Program, and ex-director of Canadian Institute for Theoretical Astrophysics (CITA). He has won numerous awards and honors including the Gruber prize in cosmology (2008). More information can be found at http://www.cita.utoronto.ca/~bond/.
