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…
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…
Spinning Effective-to-Backwards One Body (): combining Effective One-Body inspirals and Backwards One-Body merger-ringdowns for aligned spin black hole binaries
Siddharth Mahesh, Sean T. McWilliams, Zachariah Etienne
High-fidelity gravitational waveform models are essential for realizing the scientific potential of next-generation gravitational-wave observatories. While highly accurate, state-o…
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…
