Search for correlations of gamma-ray bursts with gravitational-radiation antenna pulses

Abstract

Gravitational-radiation-antenna outputs were plotted, for 20 s periods which included one gamma-ray burst trigger time. Data were obtained for two gravitational-radiation antennas. For the first 80 burst times which were studied, it is observed that either the largest or second-largest gravitational-radiation detector pulse peak occurs within 0.5 s of the gamma-ray burst trigger time for 20 of the 80 gamma-ray bursts, for the larger of the two gravitational antennas. The probability that the correlations are accidental is estimated as approximately 6.10-5.
