简介
We present the analysis of between 50 and 100 h of coincident interferometric strain data used to search for and establish an upper limit on a stochastic background of gravitational radiation. These data come from the first LIGO science run, during which all three LIGO interferometers were operated over a 2-week period spanning August and September of 2002. The method of cross correlating the outputs of two interferometers is used for analysis. We describe in detail practical signal processing issues that arise when working with real data, and we establish an observational upper limit on a f− 3 power spectrum of gravitational waves. Our 90% confidence limit is Ω 0 h 100 2<~ 23±4.6 in the frequency band 40–314 Hz, where h 100 is the Hubble constant in units of 100 km/sec/Mpc and Ω 0 is the gravitational wave energy density per logarithmic frequency interval in units of the closure density. This limit is …
