Isolated horizons of the Hopf bundle structure transversal to the null direction, the horizon equations and embeddability in NUT-like spacetimes
Denis Dobkowski-Ryłko, Jerzy Lewandowski, Maciej Ossowski
Isolated horizons that admit the Hopf bundle structure are investigated, however the null direction is allowed not to be tangent to the bundle fibres. The geomet…
Chirp mass-distance distributions of the sources of gravitational waves
Maciej Ossowski
The detection of gravitational waves emitted by binary black holes raises questions regarding the origin of binaries. There are several models in the literature involving binary ev…
Non-singular extension of the Kerr-NUT-(anti) de Sitter spacetimes
Jerzy Lewandowski, Maciej Ossowski
In 1963 Ezra Ted Newman and his two students Louis A. Tamburino, and Theodore W. J. Unti, proposed a deformation of the Shwarzschild spacetime that made it twisting. In the cosmolo…
Projectively non-singular horizons in Kerr-NUT-de Sitter spacetimes
Jerzy Lewandowski, Maciej Ossowski
It was recently discovered that Killing horizons in the generic Kerr-NUT-(anti) de Sitter spacetimes are projectively singular, i.e. their spaces of the null generators have singul…
Non-singular Kerr-NUT-de Sitter spacetimes
Jerzy Lewandowski, Maciej Ossowski
We study Killing horizons and their neighbourhoods in the Kerr-NUT-(anti-)de Sitter and the accelerated Kerr-NUT-(anti-)de Sitter spacetimes. The geometries of the horizons have an…
