Total-Variation Methods for Gravitational Waves Denoising |
|
Abstract |
We present initial results of the application of Total Variation (TV) denoising algorithms to LIGO real data. These algorithms, which do not need any a priori information about the signals, have been developed and fully tested in the context of image processing. In a recent paper we have shown the feasibility of these methods in the context of gravitational wave signals, for the considerably simpler case of signals embedded in additive Gaussian noise. Here, we apply our TV algorithms to two different types of numerically-simulated gravitational wave signals embedded in real noise, namely bursts produced from the core collapse of rotating stars and waveforms from binary black hole mergers. |
