Gravitational Waves: a new window on the Dark and Early Universe

Abstract:

In anticipation of the next generation of gravitational wave experiments and pulsar timing arrays, I will discuss the opportunities for phenomenological studies of particle physics beyond the Standard Model. I will focus on hidden gauge sectors, and discuss various astrophysical and cosmological sources of gravitational waves. I will also comment on the dark matter relic abundance and complementarity with other experimental dark sector probes in various models.
