Title: Wavelet graphs for the direct detection of gravitational waves,
Abstract: A second generation of gravitational wave detectors will soon come online
with the objective of measuring for the first time the tiny gravitational
signal from the coalescence of black hole and/or neutron star binaries. In this
communication, we propose a new time-frequency search method alternative to
matched filtering techniques that are usually employed to detect this signal.
This method relies on a graph that encodes the time evolution of the signal and
its variability by establishing links between coefficients in the multi-scale
time-frequency decomposition of the data. We provide a proof of concept for
this approach.
