Quasinormal modes and their excitation beyond general relativity. II: isospectrality loss in gravitational waveforms
Hector O. Silva, Giovanni Tambalo, Kostas Glampedakis +1
We continue our series of papers where we study the quasinormal modes, and their excitation, of black holes in the simplest beyond general relativity model in which first-principle…

Inspiral-Transition-Plunge Gravitational Waveforms Beyond Kerr: A Kerr-Newman Case Study
Daiki Watarai, Kent Yagi, Shammi Tahura
Binary black hole mergers with asymmetric component masses are key targets for both third-generation ground-based and future space-based gravitational-wave (GW) detectors, offering…

Hybrid model for inspiral-merger-ringdown gravitational waveforms from comparable-mass, nonspinning binary black holes
Nur E. M. Rifat, David A. Nichols, Kent Yagi
Gravitational waves from comparable-mass binary-black-hole mergers are often described in terms of three stages: inspiral, merger and ringdown. Post-Newtonian and black-hole pertur…
