Abstract

The question underneath this talk is: can future gravitational wave surveys be an effective tool to constrain cosmology and astrophysics?
Long story short, the answer is: yes, they will. One of the most interesting aspects in this field is the analysis of the clustering properties of black hole binary mergers, that will be mapped by future detectors in the full sky and up to very high distances.
I will discuss how hydrodynamical simulations can help modelling the clustering of such sources and, provided that the redshift cannot be directly measured from gravitational wave signals, how the use of luminosity distance space can constitute a valid alternative to build a self-consistent analysis avoiding the need of external datasets or assumptions. Finally, I will show how the tomographic analysis of binary mergers' angular power spectra can be used both to constrain cosmology and to disentangle the astrophysical or primordial origin of their progenitors.
