Gravitational Wave mergers as tracers of Large Scale Structures

Clustering measurements of Gravitational Wave (GW) mergers in Luminosity Distance Space can be used the future as a powerful tool for Cosmology. We consider tomographic Angular Power Spectrum both an Einstein Telescope-like detector network and some more advanced scenarios (more sources, better distance measurements, sky localization). produce Fisher forecasts cosmological (matter dark energy) merger bias parameters. Our fiducial model number distribution GW events is based on results from hydrodynamical simulations. The parameter with Telescope are less than those achievable near via galaxy clustering observations with, e.g., Euclid. However, we see significant improvements. Moreover, show that detected at high statistical significance. Regardless specific constraining power different experiments, many aspects make this type analysis interesting anyway. For example, compact binary by will extend up to very redshifts. Furthermore, Distortions have structure respect Redshift-Space catalogues. Finally, provide useful insight into their physical nature properties.
