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…
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…
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…
