Abstract: We examine the orbital dynamics of the planar pseudo-Newtonian Copenhagen problem, in the case of a binary system of Schwarzschild-like primaries, such as super-massive black holes. In particular, we investigate how the Jacobi constant (which… read more here.

Abstract: We study acoustic geometry in fluids with external pressure. In particular, we examine the conditions under which the acoustic metric mimics a Schwarzschild-like metric. We demonstrate that it is possible to mimic a Schwarzschild-like geometry… read more here.

DOI: 10.1103/physrevd.97.104001
Abstract: We have obtained an exact vacuum solution from a gravity sector contained in the minimal standard-model extension. The theoretical model assumes a Riemann spacetime coupled to the bumblebee field which is responsible for the spontaneous… read more here.

DOI: 10.1103/physrevd.98.104048
Abstract: In this paper a wormhole W of an especially simple—and hence, hopefully, realistic—geometry is considered: it is static, spherically symmetric, its matter source is confined to a compact neighborhood of the throat, and the tt-component… read more here.
