• Are different approaches to constructing initial data for binary black hole simulations of the same astrophysical situation equivalent?

  سند علمی۲۰۱۲Bryant Garcia, Geoffrey Lovelace, Lawrence E. Kidder, Michael Boyle

  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 to be flat) because they are easy to construct. However, CF initial data cannot simulate nearly ex

• Reducing orbital eccentricity in binary black hole simulations

  سند علمی۲۰۰۷Harald P Pfeiffer, Duncan A Brown, Lawrence E Kidder, Lee Lindblom

  Binary black hole simulations starting from quasi-circular (i.e., zero radial velocity) initial data have orbits with small but nonzero orbital eccentricities. In this paper, the quasi-equilibrium initial-data method is extended to allow nonzero radial velocities to be specified

• The Current Status of Binary Black Hole Simulations in Numerical Relativity

  سند علمی۲۰۱۰Ian Hinder

  Since the breakthroughs in 2005 which have led to long term stable solutions of the binary black hole problem in numerical relativity, much progress has been made. I present here a short summary of the state of the field, including the capabilities of numerical relativity codes,

• Reducing spurious gravitational radiation in binary-black-hole simulations by using conformally curved initial data

  سند علمی۲۰۰۸Geoffrey Lovelace

  At early times in numerical evolutions of binary black holes, current simulations contain an initial burst of spurious gravitational radiation (also called “junk radiation”) which is not astrophysically realistic. The spurious radiation is a consequence of how the binary-black-ho
