[0801.3429] Searching for stochastic gravitational-wave background with the co-located LIGO interferometers

Authors: Nickolas V Fotopoulos, for the LIGO Scientific Collaboration

Abstract: This paper presents techniques developed by the LIGO Scientific Collaboration to search for the stochastic gravitational-wave background using the co-located pair of LIGO interferometers at Hanford, WA. We use correlations between interferometers and environment monitoring instruments, as well as time-shifts between two interferometers (described here for the first time) to identify correlated noise from non-gravitational sources. We veto particularly noisy frequency bands and assess the level of residual non-gravitational coupling that exists in the surviving data.
