Non-Expanding horizons: Multipoles and the Symmetry Group
Abhay Ashtekar, Neev Khera, Maciej Kolanowski +1
It is well-known that blackhole and cosmological horizons in equilibrium situations are well-modeled by non-expanding horizons (NEHs). In the first part of the paper we introduce m…
High Precision Ringdown Modeling: Multimode Fits and BMS Frames
Lorena Magaña Zertuche, Keefe Mitman, Neev Khera +12
Quasi-normal mode (QNM) modeling is an invaluable tool for characterizing remnant black holes, studying strong gravity, and testing GR. Only recently have QNM studies begun to focu…
Testing gravitational waveform models using angular momentum
Neev Khera, Abhay Ashtekar, Badri Krishnan
The anticipated enhancements in detector sensitivity and the corresponding increase in the number of gravitational wave detections will make it possible to estimate parameters of c…
Fixing the BMS Frame of Numerical Relativity Waveforms
Keefe Mitman, Neev Khera, Dante A. B. Iozzo +9
Understanding the Bondi-Metzner-Sachs (BMS) frame of the gravitational waves produced by numerical relativity is crucial for ensuring that analyses on such waveforms are performed…
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…
