Description

In this talk I will present recent results about cross-correlation techniques between gravitational waves and galaxy catalogues. I will report on the possibility of combined near-future gravitational wave detectors and galaxy surveys constraining the origin of binary black holes, as well as the cosmic propagation law of gravitational waves. The former might shed light on whether the observed black hole binaries are of stellar or primordial origin. The latter is important for constraining deviations from general relativity on cosmological scales, because such deviations predict modified propagation of gravitational waves compared to general relativity.
