Particle Theory Seminar | Davide Racco (Stanford) “Utilizing the causal spectrum of gravity waves”
–
Abstract: The low frequency part of the gravitational wave spectrum generated by local physics, such as a phase transition, is largely fixed by causality, offering a clean window into the early Universe.Due to the difference between sub-horizon and super-horizon physics, a distinct spectral feature can allow for the direct measurement of the conformal Hubble rate at which the phase transition … Read More
