Observing complete gravitational wave signals from dynamical capture binaries
William E. East, Sean T. McWilliams, Janna Levin +1
We assess the detectability of the gravitational wave signals from highly eccentric compact binaries. We use a simple model for the inspiral, merger, and ringdown of these systems.…
The imminent detection of gravitational waves from massive black-hole binaries with pulsar timing arrays
Sean T. McWilliams, Jeremiah P. Ostriker, Frans Pretorius
Recent observations of massive galaxies indicate that they double in mass and quintuple in size between redshift z = 1 and the present, despite undergoing very little star formatio…
Universality, maximum radiation and absorption in high-energy collisions of black holes with spin
Ulrich Sperhake, Emanuele Berti, Vitor Cardoso +1
We explore the impact of black hole spins on the dynamics of high-energy black hole collisions. We report results from numerical simulations with gamma-factors up to 2.49 and dimen…
Gravitational waves and stalled satellites from massive galaxy mergers at z <= 1
Sean T. McWilliams, Jeremiah P. Ostriker, Frans Pretorius
We present a model for merger-driven evolution of the mass function for massive galaxies and their central supermassive black holes at late times. We discuss the current observatio…
Ultrarelativistic black hole formation
William E. East, Frans Pretorius
We study the ultrarelativistic head-on collision of equal mass particles, modeled as self-gravitating fluid spheres, by numerically solving the coupled Einstein-hydrodynamic equati…
Dynamical Capture Binary Neutron Star Mergers
William E. East, Frans Pretorius
We study dynamical capture binary neutron star mergers as may arise in dense stellar regions such as globular clusters. Using general-relativistic hydrodynamics, we find that these…
