Initial data for a deformed isolated horizon
Aleš Flandera, David Kofroň, Tomáš Ledvinka
Within the isolated horizon formalism, we investigate a static axisymmetric space-time of a black hole influenced by matter in its neighborhood. To illustrate the role of ingredien…
Critical phenomena in the collapse of gravitational waves
Thomas W. Baumgarte, Bernd Brügmann, Daniela Cors +6
Fine-tuning generic but smooth spherically-symmetric initial data for general relativity to the threshold of dynamical black hole formation creates arbitrarily large curvatures, me…
Universality of curvature invariants in critical vacuum gravitational collapse
Tomáš Ledvinka, Anton Khirnov
We report on a numerical study of gravitational waves undergoing gravitational collapse due to their self-interaction. We consider several families of asymptotically flat initial d…
Slicing conditions for axisymmetric gravitational collapse of Brill waves
Anton Khirnov, Tomas Ledvinka
In numerical relativity, spacetimes involving compact strongly gravitating objects are constructed as numerical solutions of Einstein's equations. Success of such a process strongl…
Disk sources of the Kerr and Tomimatsu-Sato spacetimes: construction and physical properties
Tomáš Ledvinka, Jiří Bičák
We construct the disk sources matched to the exact vacuum Kerr and to the two classes of Tomimatsu-Sato spacetimes. We analyze two models of the matter forming these disks. At each…
Rotation of inertial frames by angular momentum of matter and waves
William Barker, Tomáš Ledvinka, Donald Lynden-Bell +1
We elucidate the dynamics of a thin spherical material shell with a tangential pressure, using a new approach. This is both simpler than the traditional method of extrinsic curvatu…
