Template bank to search for exotic gravitational wave signals from astrophysical compact binaries

Understand

Modeled searches of gravitational wave signals from compact binary mergers rely on template waveforms determined by the theory of general relativity (GR).

• Once a signal is detected, one generally performs the model agnostic test of GR, either looking for consistency between the GR waveform and data or introducing phenomenological deviations to detect the departure from GR.
• The non-trivial presence of beyond-GR physics can alter the waveform and could be missed by the GR template-based searches.
