High accuracy simulations of Kerr tails: coordinate dependence and higher multipoles
Manuel Tiglio, Lawrence Kidder, Saul Teukolsky
We investigate the late time behavior of a scalar field on a fixed Kerr background using a 2+1 dimensional pseudospectral evolution code. We compare evolutions of pure axisymmetric…
Using Full Information When Computing Modes of Post-Newtonian Waveforms From Inspiralling Compact Binaries in Circular Orbit
Lawrence E. Kidder
The increasing sophistication and accuracy of numerical simulations of compact binaries (especially binary black holes) presents the opportunity to test the regime in which post-Ne…
Numerical Simulations of Oscillating Soliton Stars: Excited States in Spherical Symmetry and Ground State Evolutions in 3D
Jayashree Balakrishna, Ruxandra Bondarescu, Gregory Daues +1
Excited state soliton stars are studied numerically for the first time. The stability of spherically symmetric S-branch excited state oscillatons under radial perturbations is inve…
Finite Mirror Effects in Advanced Interferometric Gravitational Wave Detectors
Andrew P. Lundgren, Ruxandra Bondarescu, David Tsang +1
Thermal noise is expected to be the dominant source of noise in the most sensitive frequency band of second generation ground based gravitational wave detectors. Reshaping the beam…
High-accuracy comparison of numerical relativity simulations with post-Newtonian expansions
Michael Boyle, Duncan A. Brown, Lawrence E. Kidder +5
Numerical simulations of 15 orbits of an equal-mass binary black hole system are presented. Gravitational waveforms from these simulations, covering more than 30 cycles and ending…
Radiation reaction in the 2.5PN waveform from inspiralling binaries in circular orbits
Lawrence E. Kidder, Luc Blanchet, Bala R. Iyer
In this Comment we compute the contributions of the radiation reaction force in the 2.5 post-Newtonian (PN) gravitational wave polarizations for compact binaries in circular orbits…
Can Gravity Probe B usefully constrain torsion gravity theories?
Eanna E. Flanagan, Eran Rosenthal
In most theories of gravity involving torsion, the source for torsion is the intrinsic spin of matter. Since the spins of fermions are normally randomly oriented in macroscopic bod…
Evolution of the Carter constant for inspirals into a black hole: effect of the black hole quadrupole
Eanna E. Flanagan, Tanja Hinderer
We analyze the effect of gravitational radiation reaction on generic orbits around a body with an axisymmetric mass quadrupole moment Q to linear order in Q, to the leading post-Ne…
A generalization of Ryan's theorem: probing tidal coupling with gravitational waves from nearly circular, nearly equatorial, extreme-mass-ratio inspirals
Chao Li, Geoffrey Lovelace
Extreme-mass-ratio inspirals (EMRIs) and intermediate-mass-ratio inspirals (IMRIs)--binaries in which a stellar-mass object spirals into a massive black hole or other massive, comp…
Evolving relativistic fluid spacetimes using pseudospectral methods and finite differencing
Matthew D. Duez, Lawrence E. Kidder, Saul A. Teukolsky
We present a new code for solving the coupled Einstein-hydrodynamics equations to evolve relativistic, self-gravitating fluids. The Einstein field equations are solved on one grid…
Reducing orbital eccentricity in binary black hole simulations
Harald P. Pfeiffer, Duncan A. Brown, Lawrence E. Kidder +3
Binary black hole simulations starting from quasi-circular (i.e., zero radial velocity) initial data have orbits with small but non-zero orbital eccentricities. In this paper the q…
The Final Fate of Binary Neutron Stars: What Happens After the Merger?
Matthew D. Duez, Yuk Tung Liu, Stuart L. Shapiro +2
The merger of two neutron stars usually produces a remnant with a mass significantly above the single (nonrotating) neutron star maximum mass. In some cases, the remnant will be st…
