Gravity and the Search for New Physics with Cosmology
Speaker(s): Kris Sigurdson
Abstract: Despite its feeble in strength, gravity plays a pivotal role in shaping our Universe and the things in it. Ever since Newton formulated his universal law of gravitation the recognition that all things gravitate has been nearly sacrosanct. Repeatedly, apparent gravitational anomalies have either fore... read more

Cosmological Limits on Neutrino-Neutrino Scattering and Particle Physics in the Early Universe
Speaker(s): Kris Sigurdson
Abstract: In the standard model neutrinos are assumed to have streamed across the Universe since they last scattered at the weak decoupling epoch when the temperature of the standard-model plasma was ~MeV. The shear stress of free-streaming neutrinos imprints itself gravitationally on the Cosmic Microwave Bac... read more
