Charges and Fluxes on (Perturbed) Non-expanding Horizons
Abhay Ashtekar, Neev Khera, Maciej Kolanowski +1
In a companion paper we showed that the symmetry group of non-expanding horizons (NEHs) is a 1-dimensional extension of the Bondi-Metzner-Sachs group …
Comparing Remnant Properties from Horizon Data and Asymptotic Data in Numerical Relativity
Dante A. B. Iozzo, Neev Khera, Leo C. Stein +10
We present a new study of remnant black hole properties from 13 binary black hole systems, numerically evolved using the Spectral Einstein Code. The mass, spin, and recoil velocity…
Adding Gravitational Memory to Waveform Catalogs using BMS Balance Laws
Keefe Mitman, Dante A. B. Iozzo, Neev Khera +9
Accurate models of gravitational waves from merging binary black holes are crucial for detectors to measure events and extract new science. One important feature that is currently…
Inferring the gravitational wave memory for binary coalescence events
Neev Khera, Badri Krishnan, Abhay Ashtekar +1
Full, non-linear general relativity predicts a memory effect for gravitational waves. For compact binary coalescence, the total gravitational memory serves as an inferred observabl…
Compact binary coalescences: The subtle issue of angular momentum
Abhay Ashtekar, Tommaso De Lorenzo, Neev Khera
In presence of gravitational radiation, the notion of angular momentum of an isolated system acquires an infinite dimensional supertranslation ambiguity. This fact has been emphasi…
Compact binary coalescences: Constraints on waveforms
Abhay Ashtekar, Tommaso De Lorenzo, Neev Khera
Gravitational waveforms for compact binary coalescences (CBCs) have been invaluable for detections by the LIGO-Virgo collaboration. They are obtained by a combination of semi-analy…
