The Radiation Sector of NRGR
Speaker(s): Andreas Ross
Abstract: This talk will review the description of gravitational radiation in the effective field theory framework NRGR and report some recent results obtained in the radiation sector. In the matching to the radiation theory one needs to perform a multipole expansion which we present to all order. Furthermore... read more

Gravitational wave phenomenology for LIGO, LISA and co from effective field theories
Speaker(s): Andreas Ross
Abstract: The effective field theory framework yields a systematic treatment of gravitational bound states such as binary systems. Gravitational waves emitted from compact binaries are one of the prime event candidates at direct detection experiments. Due to the multiple scales involved in the binary problem,... read more

Non-Isotropy of the CMB Power Spectrum in Single Field Inflation
Speaker(s): Andreas Ross
Abstract: At large scales the CMB spectrum measured by WMAP appears to have an anomalously low power of the quadrupole and an asymmetry of power at l < 40. We show that with an initial stage of fast roll of the inflation and a gradient in the initial conditions a simple chaotic inflation model may be capable ... read more
