Abstract:

The Advanced LIGO detectors recently completed their second observation run. Here, we utilize auxiliary sensors that measure various noise sources, and use them to remove those noise contributions from the gravitational wave readout data that is used for estimation of astrophysical parameters of gravitational wave progenitors. This noise removal is particularly significant for the LIGO Hanford Observatory, where the improvement in sensitivity is greater than 20%.
