Abstract:
We describe an analysis of Apollo era lunar seismic data that looks to place an upper limit on an isotropic stochastic gravitational-wave background integrated over a year in the frequency range 0.1 Hz - 1 Hz. We find that because the moon's ambient noise background is much quieter than that of the Earth's, significant improvements over an Earth based analysis can be made. We also discuss the benefits of a potential Earth-Moon correlation search and compute the time-dependent overlap reduction function required for such an analysis. We describe preliminary results from both searches as well as conclude with discussions for future work.
