Description
In this talk I will sketch how combining new constraints from gravitational wave measurements, traditional observational bounds from cosmology and insights from theoretical particle physics allows us to test gravity with unprecedented precision, in particular zooming in on the nature of dark energy. As an explicit example, I will highlight the interplay between gravitational wave constraints from the neutron star merger GW170817, data constraints from cosmic microwave background and galaxy clustering measurements, and theoretical priors on dark energy theories from requiring them to be well-behaved and consistent at all energies.
