Abstract

I present a new method to remove detector noise from gravitationalwave (GW) interferometer data in the framework of unmodeled analyses, with special reference to coherent WaveBurst pipeline. The method introduces a pixel selection rule in the time-frequency representation of multidetector data to exclude noisy time-frequency components: this is performed multiplying each pixel by a weight function ranging from 0 to 1 and based on the coherence of the data among the detectors. Preliminary simulations indicate an improved suppression of noise with better reconstruction of both polarization components of detected GW signals.
