Avoiding closed timelike curves with a collapsing rotating null dust shell
Filipe C. Mena, Jose Natario, Paul Tod
We present an idealised model of gravitational collapse, describing a collapsing rotating cylindrical shell of null dust in flat space, with the metric of a spinning cosmic string…
Gravitational Collapse to Toroidal and Higher Genus asymptotically AdS Black Holes
Filipe C. Mena, Jose Natario, Paul Tod
We match collapsing inhomogeneous as well as spatially homogeneous but anisotropic spacetimes to vacuum static exteriors with a negative cosmological constant and planar or hyperbo…
Tangent Euler Top in General Relativity
Jose Natario
We define the tangent Euler top in General Relativity through a constrained Lagrangian on the orthonormal frame bundle. The corresponding motions are studied to various degrees of…
Homogeneous cosmologies from the quasi-Maxwell formalism
Joao Costa, Jose Natario
We show how to use the quasi-Maxwell formalism to obtain solutions of Einstein's field equations corresponding to homogeneous cosmologies - namely Einstein's universe, Godel's univ…
Newtonian limits of warp drive spacetimes
Jose Natario
We find a class of warp drive spacetimes possessing Newtonian limits, which we then determine. The same method is used to compute Newtonian limits of the Schwarzschild solution and…
