abstract = "Standard sirens are the gravitational wave (GW) analog of the
astronomical standard candles and can provide powerful information
about the dynamics of the Universe. In this work, we simulate a
catalog with 1000 standard siren events from binary neutron star
mergers, within the sensitivity predicted for the third generation
of the ground GW detector called the Einstein Telescope (ET).
After correctly modifying the propagation of GWs as input to
generate the catalog, we apply our mock dataset on scalar-tensor
theories where the speed of GW propagation is equal to the speed
of light. As a first application, we find new observational bounds
on the running of the Planck mass, when considering appropriate
values within the stability condition of the theory, and we
discuss some consequences on the amplitude of the running of the
Planck mass. In the second part, we combine our simulated standard
sirens catalog with other geometric cosmological tests (supernovae
la and cosmic chronometer measurements) to constrain the
Hu-Sawicki f (R) gravity model. We thus find new and non-null
deviations from the standard ACDM model, showing that in the
future f (R) gravity can be tested up to 95% confidence level. The
results obtained here show that the statistical accuracy
achievable by future ground-based GW observations, mainly with the
ET detector (and planned detectors with a similar sensitivity),
can provide strong observational bounds on modified gravity
theories.",
