Galactic Black Hole Binary Systems
I review observations of the X–ray spectra of Galactic Black Hole Candidates, and theoretical ideas as to how these can be produced. X–ray reflection should enable different source geometries to be distinguished, but the ionisation instability of X–ray irradiated material in hydrostatic equilibrium gives rise to large ambiguities in interpretation. It is not currently possible to determine whet...
متن کاملBinary Black Hole Accretion Flows in Merged Galactic Nuclei
We study the accretion flows from the circumbinary disks onto the supermassive binary black holes in a subparsec scale of the galactic center , using a smoothed particles hydrodynamics (SPH) code. Simulation models are presented in four cases of a circular binary with equal masses and unequal masses, and of an eccentric binary with equal masses and unequal masses. We find that the circumblack-h...
متن کاملBlack Hole Binary Dynamics
We discuss a new N-body simulation method for studying black hole binary dynamics. This method avoids previous numerical problems due to large mass ratios and trapped orbits with short periods. A treatment of relativistic effects is included when the associated time-scale becomes small. Preliminary results with up to N = 2.4×10 particles are obtained showing systematic eccentricity growth until...
متن کاملBinary black hole mergers
www.physicstoday.org After decades of effort, numerical relativists can now simulate the inspiral and merger of two black holes orbiting each other. That computational triumph has come none too soon—physicists are on the verge of detecting gravitational waves for the first time, and at long last they know what to look for. Black holes are strong-field objects whose properties are governed by Ei...
متن کاملBinary black hole spectroscopy
Abstract We study parameter estimation with post-Newtonian (PN) gravitational waveforms for the quasicircular, adiabatic inspiral of spinning binary compact objects. In particular, the performance of amplitude-corrected waveforms is compared with that of the more commonly used restricted waveforms, in Advanced LIGO and EGO. With restricted waveforms, the properties of the source can only be ext...
