we derive a new, exact solution for the Einstein-Maxwell equations that describes the collision (interaction) of two arbitrarily polarized electromagnetic shock waves. In the limit that the polarization angle vanishes, ...

New exact solutions of the vacuum Einstein field equations are constructed which describe the collision of plane gravitational waves. These solutions generalize those of Szekeres by relaxing the requirement of collinear ...

In this study we advocate the view that the cosmological constant is of electromagnetic (em) origin, which can be generated from the collision of em shock waves coupled with gravitational shock waves. The wave profiles ...

We present the metric of a Schwarzschild (S) black hole coupled to an external, stationary electromagnetic Bertotti–Robinson (BR) solution. This metric generalizes a previous metric that served to unify the S and BR ...

We make an alternative approach to Bonnorification by making use of effective Lagrangians for the gravitational fields. Using this technique we obtain a new Einstein-Maxwell solution

We show that the massive wave equation is separable in two different space—times, both arising from the collision of the cross polarized plane gravitational waves. Exact solutions can be expressed in terms of infinite series.
