Colliding Impulsive Gravitational Waves and a Cosmological Constant
C. Barrabès, P. A. Hogan
We present a space--time model of the collision of two homogeneous, plane impulsive gravitational waves (each having a delta function profile) propagating in a vacuum before collis…
Generating a Cosmological Constant with Gravitational Waves
C. Barrabès, P. A. Hogan
A technique is given to derive the well known Bell-Szekeres solution of the Einstein-Maxwell vacuum field equations describing the space-time and the Maxwell field following the he…
Collision of Shock Waves in Einstein-Maxwell Theory with a Cosmological Constant: A Special Solution
C. Barrabès, P. A. Hogan
Post-collision space-times of the Cartesian product form M'xM'', where M' and M'' are two-dimensional manifolds, are known with M' and M'' having constant curvatures of equal and o…
Collisions of Shock Waves in General Relativity
C. Barrabès, P. A. Hogan
We show that the Nariai-Bertotti Petrov type D, homogeneous solution of Einstein's vacuum field equations with a cosmological constant describes the space-time in the interaction r…
On The Interaction of Gravitational Waves with Magnetic and Electric Fields
C. Barrabes, P. A. Hogan
The existence of large--scale magnetic fields in the universe has led to the observation that if gravitational waves propagating in a cosmological environment encounter even a smal…
On Generating Gravity Waves with Matter and Electromagnetic Waves
C. Barrabes, P. A. Hogan
If a homogeneous plane light-like shell collides head-on with a homogeneous plane electromagnetic shock wave having a step-function profile then no backscattered gravitational wave…
