Convenient filtering techniques for LIGO strain of the GW150914 event
We present a new strategy for the pre-processing filtering techniques of the LIGO strain of the GW150914 [1,2] event that intends to extract as much physical information as possible, minimizing the use of prior assumptions, and avoiding intense deformations of the astrophysical signal. The new techn...

Summary: | We present a new strategy for the pre-processing filtering techniques of the LIGO strain of the GW150914 [1,2] event that intends to extract as much physical information as possible, minimizing the use of prior assumptions, and avoiding intense deformations of the astrophysical signal. The new techniques allow us to reveal more low frequency signal at earlier times, that it has been overlooked. |
