On the motion of spinning test particles in plane gravitational waves [PDF]

, 2001
The Mathisson-Papapetrou-Dixon equations for a massive spinning test particle in plane gravitational waves are analysed and explicit solutions constructed in terms of solutions of certain linear ordinary differential equations.

Collision of spinning black holes in the close limit [PDF]

, 2001
In this paper we consider the collision of spinning holes using first order perturbation theory of black holes (Teukolsky formalism). With these results (along with ones, we published in the past) one can predict the properties of the gravitational waves

Ray trajectories for a spinning cosmic string and a manifestation of self-cloaking

, 2010
A study of ray trajectories was undertaken for the Tamm medium which represents the spacetime of a cosmic spinning string, under the geometric-optics approximation. Our numerical studies revealed that: (i) rays never cross the string's boundary; (ii) the

Kerr-Sen Black Hole as Accelerator for Spinning Particles [PDF]

, 2017
It has been proved that arbitrarily high-energy collision between two particles can occur near the horizon of an extremal Kerr black hole as long as the energy $E$ and angular momentum $L$ of one particle satisfies a critical relation, which is called ...
