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…
Gravitational-wave memory effects in the Damour-Esposito-Farèse extension of Brans-Dicke theory
Shammi Tahura, David A. Nichols, Kent Yagi
Gravitational-wave memory effects are lasting changes in the strain and its time integrals. They can be computed in asymptotically flat spacetimes using the conservation and evolut…
Fundamental Physics Opportunities with the Next-Generation Event Horizon Telescope
Dimitry Ayzenberg, Lindy Blackburn, Richard Brito +45
The Event Horizon Telescope (EHT) Collaboration recently published the first images of the supermassive black holes in the cores of the Messier 87 and Milky Way galaxies. These obs…
Vacuum Spacetime With Multipole Moments: The Minimal Size Conjecture, Black Hole Shadow, and Gravitational Wave Observables
Shammi Tahura, Hassan Khalvati, Huan Yang
In this work, we explicitly construct the vacuum solution of Einstein's equations with prescribed multipole moments. By observing the behavior of the multipole spacetime metric at…
Gravitational-wave energy and other fluxes in ghost-free bigravity
Alexander M. Grant, Alexander Saffer, Leo C. Stein +1
One of the key ingredients for making binary waveform predictions in a beyond-GR theory of gravity is understanding the energy and angular momentum carried by gravitational waves a…
Science Potential for Stellar-mass Black Holes as Neighbors of Sgr A*
Shammi Tahura, Zhen Pan, Huan Yang
It has been suggested that there is possibly a class of stellar-mass black holes (BHs) residing near (distance ) the galactic center massive black hole, Sgr A*. Possibl…
