Relativistic Gravitational Collapse of a Cylindrical Shell of Dust
Ken-ichi Nakao, Yasunari Kurita, Yoshiyuki Morisawa +1
The gravitational collapse of a thick cylindrical shell of dust matter is investigated. It is found that a spacetime singularity forms on the symmetry axis and that it is necessari…
Mass and angular momenta of Kerr-anti-de Sitter spacetimes
Nathalie Deruelle
We briefly review how to compute the mass and angular momenta of rotating, asymptotically anti-de Sitter spacetimes in Einstein-Gauss-Bonnet theory of gravity using superpotentials…
Gravitational Radiation from Cylindrical Naked Singularity
Ken-ichi Nakao, Yoshiyuki Morisawa
We construct an approximate solution which describes the gravitational emission from a naked singularity formed by the gravitational collapse of a cylindrical thick shell composed…
Scalar field perturbation on six-dimensional ultra-spinning black holes
Yoshiyuki Morisawa, Daisuke Ida
We have studied the scalar field perturbations on six-dimensional ultra-spinning black holes. We have numerically calculated the quasinormal modes of rotating black holes. Our resu…
Mass and angular momenta of Kerr anti-de Sitter spacetimes in Einstein-Gauss-Bonnet theory
Nathalie Deruelle, Yoshiyuki Morisawa
We compute the mass and angular momenta of rotating anti-de Sitter spacetimes in Einstein-Gauss-Bonnet theory of gravity using a superpotential derived from standard Noether identi…
High-Speed Cylindrical Collapse of Perfect Fluid
Ken-ichi Nakao, Yoshiyuki Morisawa
The gravitational collapse of cylindrically distributed perfect fluid is studied. We assume the collapsing speed of fluid is very large and investigate such a situation by recently…
