Description
Gravitational wave observatories offers a unique view into the physics of compact object binary systems. However, the richness of astrophysical models is partially lost due to our ability of measuring a limited number of parameters from individual GW events, thus limiting our ability to break degeneracies between different models. It then becomes crucial to find alternatives ways to extract information from these datasets. The anisotropic clustering of GWs can provide such way forward. In this talk, I will discuss how by cross-correlating the spatial distribution of galaxies and BBH detected by ET/CE we can breaks such degeneracies. In particular, I will show how it is possible to constrain the time delay distribution thanks to the GW bias parameter acting as a "second clock" of the BBH population, on top of the usual "clock" given by the binary merger rate.
