Understand

We introduce a reduced basis approach as a new paradigm for modeling, representing and searching for gravitational waves.

We construct waveform catalogs for non-spinning compact binary coalescences, and we find that for accuracies of 99% and 99.999% the method generates a factor of about $10-10^5$ fewer templates than standard placement methods.
The continuum of gravitational waves can be represented by a finite and comparatively compact basis.
The method is robust under variations in the noise of detectors, implying that only a single catalog needs to be generated.
