Hyperbolicity of the Kidder-Scheel-Teukolsky formulation of Einstein's equations coupled to a modified Bona-Masso slicing condition
We show that the Kidder-Scheel-Teukolsky family of hyperbolic formulations of
the 3+1 evolution equations of general relativity remains hyperbolic when
coupled to a recently proposed modified version of the Bona-Masso slicing
condition.Comment: 4 pages. Several changes. Main corrections are in eqs. 4.9 and 4.1
The Current Status of Binary Black Hole Simulations in Numerical Relativity
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, recent physical results
obtained from simulations, and improvements to the methods used to evolve and
analyse binary black hole spacetimes.Comment: 14 pages; minor changes and corrections in response to referee
