An observational signature for extremal black holes
Stefanos Aretakis, Gaurav Khanna, Subir Sabharwal
We consider scalar perturbations of the Reissner--Nordström family and the Kerr family. We derive a characteristic expression of the radiation field, at any given unit solid angle…

Toward exponentially-convergent simulations of extreme-mass-ratio inspirals: A time-domain solver for the scalar Teukolsky equation with singular source terms
Manas Vishal, Scott E. Field, Katie Rink +2
Gravitational wave signals from extreme mass ratio inspirals are a key target for space-based gravitational wave detectors. These systems are typically modeled as a distributionall…

Angular Momentum for Black Hole Binaries in Numerical Relativity
Ritesh Bachhar, Richard Price, Gaurav Khanna
The extensive catalog of waveforms, with details of binary black hole inspiral and merger, offer an opportunity to understand black hole interactions beyond the large separation re…
