Light propagation and quasinormal modes of a topologically charged Schwarzschild-Klinkhamer wormhole
C. F. S. Pereira, H. Belich, A. R. Soares +3
In this work, we present a theoretical analysis of null geodesics, critical photon orbits, and shadow formation associated with a wormhole generated by a geometric defect. The prop…
Light deflection and gravitational lensing effects inspired by loop quantum gravity
A. R. Soares, C. F. S. Pereira, R. L. L. Vitória +2
In the present work, we theoretically investigate light deflection in the weak and strong field regimes for two regular spacetimes with corrections from loop quantum gravity. We tr…
Topologically Charged Holonomy corrected Schwarzschild black hole lensing
A. R. Soares, R. L. L. Vitória, C. F. S. Pereira
In this paper, we theoretically investigate the deflection of light produced by a topologically charged Holonomy corrected Schwarzschild black hole. The study is carried out both i…
On the Klein-Gordon oscillators in Eddington-inspired Born-Infeld gravity global monopole spacetime and a Wu-Yang magnetic monopole
Omar Mustafa, Adriano R. Soares, Carlos F. S. Pereira +1
We consider Klein-Gordon (KG) particles in a global monopole (GM) spacetime within Eddington-inspired Born-Infeld gravity (EiBI-gravity) and in a Wu-Yang magnetic monopole (WYMM).…
Holonomy corrected Schwarzschild black hole lensing
A. R. Soares, C. F. S. Pereira, R. L. L. Vitória
In the present work, we theoretically investigate gravitational lensing in the spacetime of a holonomy corrected Schwarzschild black hole. Analytical expressions for the light defl…
Gravitational lensing in a topologically charged Eddington-inspired Born-Infeld spacetime
A. R. Soares, R. L. L. Vitória, C. F. S. Pereira
In the present paper, we study several aspects of gravitational lensing caused by a topologically charged Monopole/Wormhole, both in the weak field limit and in the strong field li…
