Does non-stationary noise in LIGO and Virgo affect the estimation of $H_0$?

Understand

Gravitational-wave observations of binary neutron star mergers and their electromagnetic counterparts provide an independent measurement of the Hubble constant, $H_0$, through the standard-sirens approach.

• Current methods of determining $H_0$, such as measurements from the early universe and the local distance ladder, are in tension with one another.
• If gravitational waves are to break this tension a thorough understanding of systematic uncertainty for gravitational-wave observations is required.
• To accurately estimate the properties of gravitational-wave signals measured by LIGO and Virgo, we need to understand the characteristics of the detectors noise.
