Seminarium "High Energy, Cosmology and Astro-particle Physics (HECA)"

Online meeting! The 2015 observation of gravitational waves opened up a new window into particle physics. First order cosmological phase transitions are predicted in many extensions of the standard model of particle physics and can generate gravitational wave signatures. Exciting recent results mean that we have now entered an era where data from gravitational wave experiments may be used as possible signals or constraints on particle physics theories. I will discuss these and show how to determine gravitational wave constraints, signals and future discovery projections using the state-of-the-art methods. I will critically evaluate many approximations used in the literature and discuss substantial sources of uncertainty and unknowns.
