[H20.011] Gravitational gradients in gravitational wave detectors: data analysis methods

David Garrison, Gabriela Gonzalez, Gaurav Khanna (Center for Gravitational Physics and Geometry, The Pennsylvannia State University, University Park, PA 16802)

We present a method of analyzing seismic data at the sites of gravitational wave detectors to determine the possible influence of gravitational gradients as a noise source in the detectors. We use statistical methods to distinguish between local and gobal noise sources, as well as compare our findings to models of gravitational gradients (S. A. Hughes and K. S. Thorne, Physical Review D, Volume 58, 122002). We apply these methods to data taken at the Hanford LIGO site, and present preliminary results.

This work was supported by Pennsylvannia State University and the National Science Foundation. We acknowledge the collaboration of the LIGO project while taking the data presented.
