Gravitational waves - a new probe of the early Universe — •Valerie Domcke — CERN, Geneva, Switzerland

Due to their extremely weak interactions with the matter content of the Universe, gravitational waves generated right after the Big Bang can traverse the Universe basically unperturbed, carrying information about their production processes and the expansion history of our Universe. This makes them a unique probe of BSM physcis at very high energies. I will talk about possible next steps in this field, including the search for the stochastic gravitational wave background and new ideas for searching for gravitational waves at ultra-high frequencies.
