A new measure for the comparison of signals without templates and the detection of gravitational polarization in the GW150914 event
Abstract
We present a new measure for the comparison of unknown gravitational wave signals in two detectors, without recurring to an a priori template. We apply this measure to the LIGO data of the GW150914 event and discover that Hanford and Livingston observatories have recorded two different components of the gravitational wave polarization signal.
