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…
Closed Timelike Curves and "Effective" Superluminal Travel with Naked Line Singularities
Caroline Mallary, Gaurav Khanna, Richard Price
We examine closed timelike curves (CTCs) and "effective" superluminal travel in a spacetime containing naked line singularities, which we call "wires". Each wire may be straight-li…
Scalar Fields in Black Hole Spacetimes
Izak Thuestad, Gaurav Khanna, Richard Price
The time-evolution of matter fields in black hole exterior spacetimes is a well-studied subject, spanning several decades of research. However, the behavior of fields in the black…
Gravitational wave sources: reflections and echoes
Richard Price, Gaurav Khanna
The recent detection of gravitational waves has generated interest in alternatives to the black hole interpretation of sources. One set of such alternatives involves a prediction o…
Black Hole Ringing, Quasinormal Modes, and Light Rings
Gaurav Khanna, Richard H. Price
Modelling of gravitational waves from binary black hole inspiral has played an important role in the recent observations of such signals. The late-stage ringdown phase of the gravi…
Arrival Times of Gravitational Radiation Peaks for Binary Inspiral
Richard H Price, Gaurav Khanna
Modeling of gravitational waves (GWs) from binary black hole inspiral brings together early post-Newtonian waveforms and late quasinormal ringing waveforms. Attempts to bridge the…
