Abstract

Forecast constraints for a symmetric teleparallel gravity model with a $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ background are made using forthcoming ground and space based gravitational waves observatories. A Bayesian analysis resorting to generated mock catalogs shows that LIGO-Virgo is not expected to be able to distinguish this model from $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$, while both LISA and the ET will, with the ET outperforming LISA. We also show that low redshift events are favored in order to improve the quality of the constrains.
