Head-on Collisions of Boson Stars with Bowen-York Type Initial Data
Jake Doherty, Pablo Laguna
We present a numerical relativity study of head-on collisions involving boson stars using initial data inspired by the Bowen-York initial data used to model black hole binaries wit…
Growth of a Black Hole in a Scalar Field Cosmology
Jake Doherty, Miguel Gracia-Linares, Pablo Laguna
We present a numerical relativity study of the accretion properties of a non-spinning black hole in a cosmology driven by a scalar field. The simulations are carried out with a mod…
Black Hole - Neutron Star Binary Mergers: The Impact of Stellar Compactness
Bing-Jyun Tsao, Bhavesh Khamesra, Miguel Gracia-Linares +1
Recent gravitational wave observations include possible detections of black hole - neutron star binary mergers. As with binary black hole mergers, numerical simulations help charac…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Second MAYA Catalog of Binary Black Hole Numerical Relativity Waveforms
Deborah Ferguson, Evelyn Allsup, Surendra Anne +14
Numerical relativity waveforms are a critical resource in the quest to deepen our understanding of the dynamics of, and gravitational waves emitted from, merging binary systems. We…
Grazing Collisions of Black Holes via the Excision of Singularities
Steve Brandt, Randall Correll, Roberto Gomez +10
We present the first simulations of non-headon (grazing) collisions of binary black holes in which the black hole singularities have been excised from the computational domain. Ini…
Approximate Analytical Solutions to the Initial Data Problem of Black Hole Binary Systems
P. Marronetti, M. Huq, P. Laguna +4
We present approximate analytical solutions to the Hamiltonian and momentum constraint equations, corresponding to systems composed of two black holes with arbitrary linear and ang…
Dynamics of scalar fields in the background of rotating black holes II: A note on superradiance
Nils Andersson, Pablo Laguna, Philippos Papadopoulos
We analyze the amplification due to so-called superradiance from the scattering of pulses off rotating black holes as a numerical time evolution problem. We consider the "worst pos…
Stable characteristic evolution of generic 3-dimensional single-black-hole spacetimes
The Binary Black Hole Grand Challenge Alliance, :, R. Gomez +42
We report new results which establish that the accurate 3-dimensional numerical simulation of generic single-black-hole spacetimes has been achieved by characteristic evolution wit…
Dynamics of perturbations of rotating black holes
W. Krivan, P. Laguna, P. Papadopoulos +1
We present a numerical study of the time evolution of perturbations of rotating black holes. The solutions are obtained by integrating the Teukolsky equation written as a first-ord…
Dynamics of Scalar Fields in the Background of Rotating Black Holes
W. Krivan, P. Laguna, P. Papadopoulos
A numerical study of the evolution of a massless scalar field in the background of rotating black holes is presented. First, solutions to the wave equation are obtained for slowly…
