To investigate the model and extra frictional effects in standard siren simulation of $f(Q)$ cosmologies, we simulated three types of standard siren data based on different fiducial models ($\Lambda$CDM and $f(Q)$ models). Both effects are important in standard siren simulation. Explicitly, the $f(Q)_P$ and $f(Q)_E$ models need more observational data (e.g.growth factor) to further study. The $f(Q)_{PE}$ model could be ruled out by the EM data. And both the $f(Q)_{HT}$ models will be excluded by the future standard siren data.

    gr-qc 2025-09 conditional novelty 4.0

    Reconstructing the dark energy density from DESI BAO and DESyr5 supernovae, then recasting it as f(Q) gravity, predicts a low-redshift gravitational wave damping ν≈0.18 (≳2σ from GR) only for the DESyr5 dataset.
