I present a new method to remove detector noise from gravitational- wave (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.

Abstract

I present a new method to remove detector noise from gravitational- wave (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.
