MICROLENSING BY HARKO-KOVACS-LOBO PHANTOM WORMHOLE

Abstract

This work investigates gravitational microlensing by a phantom wormhole. Gravitational microlensing is the effect of light bending in a gravitational field, in which one or more images of a light source appear and, in a particular case, an Einstein ring may appear. Gravity microlensing can be used as a possible observation method to detect or rule out the existence of wormholes. In this work, the Harko–Kovax–Lobo (HKL) wormhole will be examined as a lens. Using the lens equation and the definition of the Einstein radius, we find the angular positions of the physical image inside and outside the Einstein ring. The work contains a comparative analysis of the light curves of the Schwarzschild black hole and the HKL wormhole.
