Towards Simulations of 3d Black Hole Coalescence
I review recent developments in numerical relativity, focussing on progress made in 3D black hole evolution. Progress in development of black hole initial data, apparent horizon boundary conditions, adaptive mesh refinement, and characteristic evolution is highlighted, as well as full 3D simulations of colliding and distorted black holes. For true 3D distorted holes, with Cauchy evolution techn...
متن کاملGravitational-wave data analysis using binary black-hole waveforms
While the inspiral and ring-down stages of the binary black-hole coalescence are well-modelled by analytical approximation methods in general relativity, the recent progress in numerical relativity has enabled us to compute accurate waveforms from the merger stage also. This has an important impact on the search for gravitational waves from binary black holes. ‘Complete’ binary black-hole wavef...
متن کاملThe Afterglow of Massive Black Hole Coalescence
The final merger of a pair of massive black holes in a galactic nucleus is compelled by gravitational radiation. Gravitational waves from the mergers of black holes of masses 105−7(1 + z)M⊙ at redshifts of 1 − 20 will be readily detectable by the Laser Interferometer Space Antenna (LISA), but an electromagnetic afterglow would be helpful in pinpointing the source and its redshift. Long before t...
متن کاملCoalescence of Black Hole-Neutron Star Binaries
We review the current status of general relativistic studies for the coalescence of black hole-neutron star (BH-NS) binaries. First, procedures for a solution of BH-NS binaries in quasi-equilibrium circular orbits and the numerical results, such as quasi-equilibrium sequence and mass-shedding limit, of the high-precision computation, are summarized. Then, the current status of numerical-relativ...
