We give a brief review on the formation and the calculation of black hole shadows. Firstly, we introduce the concept of a black hole shadow and the current works on a variety of black …
Shadows and gravitational weak lensing by the Schwarzschild black hole in the string cloud background with quintessential field - IOPscience This site uses cookies. By continuing to use …
In this study, the gravitational deflection angle of photons in the weak field limit (or the weak deflection angle) and shadow cast by the electrically charged and spherically symmetric …
This paper is devoted to studying thermodynamics and particle acceleration around charged rotating BHs surrounded by perfect fluid dark matter. In the beginning, we discuss BH …
We study shadows cast by a certain class of rotating wormholes and point out the crucial role of a rotating wormhole throat in the formation of a shadow. Overlooking this crucial role …

Abstract The Event Horizon Telescope (EHT), a global submillimeter wavelength very long baseline interferometry array, unveiled event-horizon–scale images of the supermassive …
The Newman-Janis (NJ) algorithm has been extensively used in the literature to generate rotating black hole solutions from nonrotating seed spacetimes. In this work, we show, using …
We investigate the null geodesics and the shadow cast by the Kerr–Newman–Kiselev– Letelier (KNKL) black hole for the equation of state parameter\(\omega _q=-2/3\) and for …
