This colloquium will be given by Ira Rothstein of Carnegie Mellon University.
Abstract: The utility of gravitational wave astronomy is predicated on our ability to make precise predictions for the signals as functions of the mass, spin and internal structure of the components of binary inspirals. In this talk I will discuss the latest results in analytic calculations of gravitational wave forms which are derived from first principle techniques developed from an effective field theory with a non-trivial classical renormalization group flow. Along the way I will show how modern amplitude techniques can be utilized to calculate Post-Newtonian potentials and how solutions to Einsteins equations can be generated directly from the S matrix with no recourse to an action or equations of motion. Finally I will present A puzzle about black holes which arises in this theory.
