Degeneracy in exotic gravitational lensing
Margarita Safonova, Diego F. Torres
We present three different theoretically foreseen, but unusual, astrophysical situations where the gravitational lens equation ends up being the same, thus producing a degeneracy p…
Motion of a Vector Particle in a Curved Spacetime. I. Lagrangian Approach
Zafar Turakulov, Margarita Safonova
From the simple Lagrangian the equations of motion for the particle with spin are derived. The spin is shown to be conserved on the particle world-line. In the absence of a spin th…
Microlensing by natural wormholes: theory and simulations
Margarita Safonova, Diego F. Torres, Gustavo E. Romero
We provide an in depth study of the theoretical peculiarities that arise in effective negative mass lensing, both for the case of a point mass lens and source, and for extended sou…
