Tracing the large scale structure of the Universe using gravitational waves

Abstract

During the next decade there will be an unprecedented opportunity to combine data coming from galaxy surveys and gravitational wave observatories to address open questions in Cosmology. In this talk I will present some recently developed numerical tools that allow to estimate the cosmological signal generated by both resolved gravitational waves events and by a stochastic gravitational wave background. I will also present a worked example in which the cross correlation of large-scale structure and gravitational waves data is used to establish whether the black holes detected by LIGO have an astrophysical or primordial origin.
