Abstract / Description:We have developed a procedure for the search of signals from periodic sources in the data of gravitational wave detectors. We report here the analysis of one year of data from the resonant detector Explorer, searching for sources located in the Galactic Center (GC). No signals with amplitude greater than h-bar = 2.9×10–24, in the range 921.32–921.38 Hz, were observed using data collected over a time period of 95.7 days, for a source located at alpha= 17.70±0.01 h and delta= –29.00±0.05 deg. Our procedure can be extended for any assumed position in the sky and for a more general all-sky search, with the proper frequency correction to account for the spin-down and Doppler effects.
