Description
I will present our recent work where we detected for the first time cross-correlations between gravitational wave sources and galaxies, at 5.9$\sigma$. We analysed the GWTC-3 and GLADE+ catalogs with a novel technique called Peak Sirens. We obtained the first measurement of the Hubble constant from this method, and the first bounds whatsoever on the gravitational wave clustering bias. This work opens a new window for analysing GW sources as tracers of the large scale structures.
