Three-dimensional relativistic simulations of rotating neutron-star collapse to a Kerr black hole

- L. Baiotti, I. Hawke, +5 authors E. Seidel
- Physics
- 6 March 2004

We present a new three-dimensional fully general-relativistic hydrodynamics code using high-resolution shock-capturing techniques and a conformal traceless formulation of the Einstein equations.… Expand

Gravitational waves from the Papaloizou-Pringle instability in black-hole-torus systems.

We present a new three-dimensional general relativistic hydrodynamics code, the Whisky code. This code incorporates the expertise developed over the past years in the numerical solution of Einstein… Expand

Collapse of nonlinear gravitational waves in moving-puncture coordinates

- D. Hilditch, T. Baumgarte, +4 authors E. Mueller
- Physics
- 19 September 2013

We study numerical evolutions of nonlinear gravitational waves in moving-puncture coordinates. We adopt two different types of initial data\char22{}Brill and Teukolsky waves\char22{}and evolve them… Expand

Oscillations of vertically integrated relativistic tori – II. Axisymmetric modes in a Kerr space–time

- P. J. Montero, L. Rezzolla, S. Yoshida
