Impact of calibration uncertainties on Hubble constant measurements from gravitational-wave sources*

Gravitational-wave detections of electromagnetically bright compact binary coalescences can provide an independent measurement of the Hubble constant $H_0$ with the standard siren method. In order to obtain a measurement that could help arbitrating the existing tension on $H_0$, one needs to fully understand any source of systematic biases for this approach. In this talk, we present results for our study that investigates the impact of instrumental calibration errors on the inferred Hubble constant results. We simulate binary neutron star mergers detected by the network of Advanced LIGO and Advanced Virgo interferometers at their design sensitivities. We artificially add exceptionally large calibration errors as experienced in LIGO-Virgo's third observing run, and we will present the $H_0$ measurements after combining multiple events.
