Cauchy horizon stability in self-similar collapse: scalar radiation
Brien C Nolan, Thomas J Waters
The stability of the Cauchy horizon in spherically symmetric self-similar collapse is studied by determining the flux of scalar radiation impinging on the horizon. This flux is fou…
Naked singularities in cylindrical collapse of counter-rotating dust shells
Brien C. Nolan
Solutions describing the gravitational collapse of asymptotically flat cylindrical and prolate shells of (null) dust are shown to admit globally naked singularities.
Geometry and topology of singularities in spherical dust collapse
Brien C. Nolan, Filipe C. Mena
We derive some more results on the nature of the singularities arising in the collapse of inhomogeneous dust spheres. (i) It is shown that there are future-pointing radial and non-…
Interaction of High-Velocity Pulsars with Supernova Remnant Shells
E. van der Swaluw, A. Achterberg, Y. A. Gallant +2
Hydrodynamical simulations are presented of a pulsar wind emitted by a supersonically moving pulsar. The pulsar moves through the interstellar medium or, in the more interesting ca…
