Modeling Compact Binary Merger Waveforms Beyond General Relativity

Understand

The parameterized post-Einsteinian framework modifies inspiral waveform models to incorporate effects beyond General Relativity.

• We extend the existing model into the merger-ringdown regime.
• The modification introduced here adds a single degree of freedom that corresponds to a change in the binary coalescence time.
• Other merger properties remain as predicted by GR.
