Discriminating Cosmological Expansion Models With Third Generation Gravitational Waves Detectors
Gravitational Waves, Standard Sirens, Bayesian Model Selection, Einstein Telescope.
At the dawn of Gravitational Wave Astronomy, new avenues have been opened to test and
constrain cosmological models. By simulating standard sirens detected by the third generation ground-
based gravitational wave detector, Einstein Telescope, we show how we one can discriminate among
different cosmological models. In this work, we use 10-year projected data of Einstein Telescope to compare
the standard cosmological model (the Lambda CDM) with models using different phenomenological
parametrizations of the equation of state for the dark energy.
