The Direct Wave is Not a Meaningful Test of Horizon Properties
Anuj Kankani, Sean T. McWilliams
Recently, a distinct non--quasinormal mode component of black hole binary merger radiation, named the direct wave, has been identified. The frequency and damping time of the direct…
Direct Waves in Black-Hole Binary Mergers: Insights from the Backwards One Body Model
Anuj Kankani, Sean T. McWilliams
The merger-ringdown radiation from a black hole binary merger is accurately modeled by a sum of linear quasinormal modes (QNMs). Recently, a non-QNM ``direct wave" component of the…
Modeling Relative Peak Times of Gravitational Wave Harmonics
Anuj Kankani, Sean T. McWilliams
Accurate modeling of gravitational waves from binary black hole mergers is essential for extracting their rich physics. A key detail for understanding the physics of mergers is pre…
BOB the (Waveform) Builder: Optimizing Analytical Black-Hole Binary Merger Waveforms
Anuj Kankani, Sean T. McWilliams
The Backwards-One-Body (BOB) model provides a fully analytical and physically motivated description of the merger-ringdown gravitational radiation emanating from a black hole binar…
