Comparison of electromagnetic and gravitational radiation; what we can learn about each from the other
Richard H. Price, John W. Belcher, David A. Nichols
We compare the nature of electromagnetic fields and of gravitational fields in linearized general relativity. We carry out this comparison both mathematically and visually. In part…
Branching of quasinormal modes for nearly extremal Kerr black holes
Huan Yang, Fan Zhang, Aaron Zimmerman +3
We show that nearly extremal Kerr black holes have two distinct sets of quasinormal modes, which we call zero-damping modes (ZDMs) and damped modes (DMs). The ZDMs exist for all ha…
Black hole-neutron star mergers at realistic mass ratios: Equation of state and spin orientation effects
Francois Foucart, M. Brett Deaton, Matthew D. Duez +7
Black hole-neutron star mergers resulting in the disruption of the neutron star and the formation of an accretion disk and/or the ejection of unbound material are prime candidates…
Dynamical Excision Boundaries in Spectral Evolutions of Binary Black Hole Spacetimes
Daniel A. Hemberger, Mark A. Scheel, Lawrence E. Kidder +4
Simulations of binary black hole systems using the Spectral Einstein Code (SpEC) are done on a computational domain that excises the regions inside the black holes. It is imperativ…
Prospects for probing strong gravity with a pulsar-black hole system
N. Wex, K. Liu, R. P. Eatough +3
The discovery of a pulsar (PSR) in orbit around a black hole (BH) is expected to provide a superb new probe of relativistic gravity and BH properties. Apart from a precise mass mea…
Suitability of hybrid gravitational waveforms for unequal-mass binaries
Ilana MacDonald, Abdul H. Mroue, Harald P. Pfeiffer +5
This article studies sufficient accuracy criteria of hybrid post-Newtonian (PN) and numerical relativity (NR) waveforms for parameter estimation of strong binary black-hole sources…
A geometrically motivated coordinate system for exploring spacetime dynamics in numerical-relativity simulations using a quasi-Kinnersley tetrad
Fan Zhang, Jeandrew Brink, Béla Szilágyi +1
We investigate the suitability and properties of a quasi-Kinnersley tetrad and a geometrically motivated coordinate system as tools for quantifying both strong-field and wave-zone…
Vacuum Instability in Chern-Simons Gravity
Sergei Dyda, Eanna E. Flanagan, Marc Kamionkowski
We explore perturbations about a Friedmann-Robertson-Walker background in Chern-Simons gravity. At large momenta one of the two circularly polarized tensor modes becomes ghostlike.…
Resonantly enhanced and diminished strong-field gravitational-wave fluxes
Eanna E. Flanagan, Scott A. Hughes, Uchupol Ruangsri
The inspiral of a stellar mass () compact body into a massive () black hole has been a focus of much effort, both for the promise of such sy…
Visualizing Spacetime Curvature via Frame-Drag Vortexes and Tidal Tendexes III. Quasinormal Pulsations of Schwarzschild and Kerr Black Holes
David A. Nichols, Aaron Zimmerman, Yanbei Chen +5
In recent papers, we and colleagues have introduced a way to visualize the full vacuum Riemann curvature tensor using frame-drag vortex lines and their vorticities, and tidal tende…
Visualizing Spacetime Curvature via Frame-Drag Vortexes and Tidal Tendexes II. Stationary Black Holes
Fan Zhang, Aaron Zimmerman, David A. Nichols +5
When one splits spacetime into space plus time, the Weyl curvature tensor (which equals the Riemann tensor in vacuum) splits into two spatial, symmetric, traceless tensors: the tid…
Are different approaches to constructing initial data for binary black hole simulations of the same astrophysical situation equivalent?
Bryant Garcia, Geoffrey Lovelace, Lawrence E. Kidder +4
Initial data for numerical evolutions of binary-black holes have been dominated by "conformally flat" (CF) data (i.e., initial data where the conformal background metric is chosen…
Numerical simulations with a first order BSSN formulation of Einstein's field equations
J. David Brown, Peter Diener, Scott E. Field +7
We present a new fully first order strongly hyperbolic representation of the BSSN formulation of Einstein's equations with optional constraint damping terms. We describe the charac…
Prototype effective-one-body model for nonprecessing spinning inspiral-merger-ringdown waveforms
Andrea Taracchini, Yi Pan, Alessandra Buonanno +6
We first use five non-spinning and two mildly spinning (chi_i \simeq -0.44, +0.44) numerical-relativity waveforms of black-hole binaries and calibrate an effective-one-body (EOB) m…
