On space-times admitting shear-free, irrotational, geodesic null congruences
A. M. Sintes, A. A. Coley, D. J. McManus
Space-times admitting a shear-free, irrotational, geodesic null congruence are studied. Attention is focused on those space-times in which the gravitational field is a combination…
Shear-free, Irrotational, Geodesic, Anisotropic Fluid Cosmologies
Des J. Mc Manus, Alan A. Coley
General relativistic anisotropic fluid models whose fluid flow lines form a shear-free, irrotational, geodesic timelike congruence are examined. These models are of Petrov type D,…
On Spacetimes Admitting Shear-free, Irrotational, Geodesic Timelike Congruences
Alan A. Coley, Des J. Mc Manus
A comprehensive analysis of general relativistic spacetimes which admit a shear-free, irrotational and geodesic timelike congruence is presented. The equations governing the models…
Weak-Field Gravity of Revolving Circular Cosmic Strings
Des J. Mc Manus, Michel A. Vandyck
A weak-field solution of Einstein's equations is constructed. It is generated by a circular cosmic string revolving in its plane about the centre of the circle. (The revolution is…
Weak-Field Gravity of Circular Cosmic Strings
Shane J. Hughes, Des J. Mc Manus, Michel A. Vandyck
A weak-field solution of Einstein's equations is constructed. It is generated by a circular cosmic string externally supported against collapse. The solution exhibits a conical sin…
