Abstract:

We propose a novel approach to the autonomous detection and reconstruction of a gravitational wave bursts by an intercontinental network of six resonant antennae. Our method consists first in determining the arrival times in at least three antennae and then in recombining the responses of all the six antennae on the same wavefront. The method gives amplitude, direction of propagation and polarization of the burst. In addition it provides a linear and a cubic veto that effectively reject as spurious non gravitational wave bursts those signals which are not traceless and transverse.
