Gravitational Waves in High Energy Fixed-Target Collisions

D. V. Fursaev, V. A. Tainov

The gravitational field of two-body system, a high energetic particle and a massive particle at rest, is studied in the linearized Einstein gravity. The ultrarelativistic particle…

Fast Radio Bursts and Electromagnetic Transition Radiation on Gravitational Shockwaves

D. V. Fursaev, E. A. Davydov, V. A. Tainov

When a gravitational shockwave hits a magnetar it creates perturbations of the magnetar magnetic field in a form of a transition radiation. We argue that this radiation can be a no…

Perturbations of classical fields by gravitational shockwaves

D. V. Fursaev, E. A. Davydov, I. G. Pirozhenko +1

Gravitational shockwaves are geometries where components of the transverse curvature have abrupt behaviour across null hypersurfaces, which are fronts of the waves. We develop a ge…

A Note on Stress-Energy Tensor and Variational Principle for Null Strings

E. A. Davydov, D. V. Fursaev, V. A. Tainov

A straightforward application of the variational principle to null strings meets difficulties since string's world-sheets are degenerate. It is known that the variational principle…

Null Cosmic Strings: Scattering by Black Holes, Optics and Spacetime Content

E. A. Davydov, D. V. Fursaev, V. A. Tainov

Equations of motion of null cosmic strings near black holes, or other massive sources, are solved exactly in the weak field approximation. The stress-energy tensor of a null string…
