Gravitational Wave mergers as tracers of Large Scale Structures

Understand

Clustering measurements of Gravitational Wave (GW) mergers in Luminosity Distance Space can be used in the future as a powerful tool for Cosmology.

• We consider tomographic measurements of the Angular Power Spectrum of mergers both in an Einstein Telescope-like detector network and in some more advanced scenarios (more sources, better distance measurements, better sky localization).
• We produce Fisher forecasts for both cosmological (matter and dark energy) and merger bias parameters.
• Our fiducial model for the number distribution and bias of GW events is based on results from hydrodynamical simulations.
