Implications of Dedicated Seismometer Measurements on Newtonian-Noise Cancellation for Advanced LIGO

Coughlin, Michael W.; Harms, Jan; Driggers, Jennifer C.; McManus, David; Mukund, Nikhil; Ross, M. P.; Slagmolen, Bram; Venkateswara, Krishna Yethadka


Newtonian gravitational noise from seismic fields will become a limiting noise source at low frequency for second-generation, gravitational-wave detectors. It is planned to use seismic sensors surrounding the detectors' test masses to coherently subtract Newtonian noise using Wiener filters derived from the correlations between the sensors and detector data. In this Letter, we use data from a seismometer array deployed at the corner station of the Laser Interferometer Gravitational Wave...[Show more]
