Geodesic congruences, impulsive gravitational waves and gravitational memory
Martin O'Loughlin, Hovhannes Demirchian
In this paper we introduce a new approach to the study of the effects that an impulsive wave, containing a mixture of material sources and gravitational waves, has on a geodesic co…

On integrability of geodesics in near-horizon extremal geometries: Case of Myers-Perry black holes in arbitrary dimensions
Hovhannes Demirchian, Armen Nersessian, Saeedeh Sadeghian +1
We investigate dynamics of probe particles moving in the near-horizon limit of extremal Myers-Perry black holes in arbitrary dimensions. Employing ellipsoidal coordinates we show t…
