Forecasting F(Q) cosmology with ΛCDM background using standard sirens

J. Ferreira, T. Barreiro, J. P. Mimoso, N. J. Nunes

Forecast constraints for a symmetric teleparallel gravity model with a ΛCDM 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 ΛCDM, 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.
