On characteristic initial data for a star orbiting a black hole

Nigel T. Bishop, Roberto Gomez, Luis Lehner +2

We take further steps in the development of the characteristic approach to enable handling the physical problem of a compact self-gravitating object, such as a neutron star, in clo…

On the existence of initial data containing isolated black holes

Sergio Dain, Jose Luis Jaramillo, Badri Krishnan

We present a general construction of initial data for Einstein's equations containing an arbitrary number of black holes, each of which is instantaneously in equilibrium. Each blac…

Modeling the Black Hole Excision Problem

B. Szilagyi, H-O. Kreiss, J. Winicour

We analyze the excision strategy for simulating black holes. The problem is modeled by the propagation of quasi-linear waves in a 1-dimensional spatial region with timelike outer b…

New class of post-Newtonian approximants to the waveform templates of inspiralling compact binaries: Test-mass in the Schwarzschild spacetime

P. Ajith, Bala R. Iyer, C. A. K. Robinson +1

(Abridged): The standard adiabatic approximation to phasing of gravitational waves from inspiralling compact binaries uses the post-Newtonian expansions of the binding energy and g…

Testing the Master Constraint Programme for Loop Quantum Gravity I. General Framework

Bianca Dittrich, Thomas Thiemann

Recently the Master Constraint Programme for Loop Quantum Gravity (LQG) was proposed as a classically equivalent way to impose the infinite number of Wheeler -- DeWitt constraint e…
