We consider reflection-asymmetric thin-shell wormholes within Palatini f(R) gravity using a matching procedure of two patches of electrovacuum space-times at a hypersurface (the shell) via suitable junction conditions. The conditions for having (linearly) stable wormholes supported by positive-energy matter sources are determined. We also identify some subsets of parameters able to locate the shell radius above the event horizon (when present) but below the photon sphere (on both sides). We… 
Observational signature and additional photon rings of an asymmetric thin-shell wormhole
Recently, a distinct shadow mechanism was proposed by Wang et al. from the asymmetric thin-shell wormhole (ATW) in [Phys. Lett. B 811 (2020) 135930]. On the other hand, Gralla et al’s work [Phys.
Gravitational lensing by two photon spheres in a black-bounce spacetime in strong deflection limits
We investigate gravitational lensing by a primary photon sphere which is formed by unstable circular light orbits, and by a secondary photon sphere on a wormhole throat in a black-bounce spacetime
Photon spheres and spherical accretion image of a hairy black hole
In this paper, we first consider null geodesics of a class of charged, spherical and asymptotically flat hairy black holes in an Einstein-Maxwell-scalar theory with a non-minimal coupling for the
Retrolensing by two photon spheres of a black-bounce spacetime
We investigate retrolensing by two photon spheres in a novel black-bounce spacetime suggested by Lobo et al. which can correspond to a Schwarzschild black hole, a regular black hole, and a
Shadows and optical appearance of black bounces illuminated by a thin accretion disk
We study the light rings and shadows of an uniparametric family of spherically symmetric geometries interpolating between the Schwarzschild solution, a regular black hole, and a traversable wormhole,
Shadows and rings of the Kehagias-Sfetsos black hole surrounded by thin disk accretion
In this paper, under the illumination of thin disk accretion, we have employed the ray-tracing method to carefully investigate shadows and rings of the Kehagias-Sfetsos(KS) black hole in deformed
Effects of dark matter on shadows and rings of Brane-World black holes illuminated by various accretions
In this study, by taking the accretions into account, the observed shadows and rings cast by the Brane-World black hole were numerically investigated when the observer was located at the cosmological
Revisiting the shadow of braneworld black holes
We revisit the shadows of rotating braneworld black holes in the Randall-Sundrum type II model, by considering not only the metric in the near region of the black hole but also the linearized metric
Photon ring and observational appearance of a hairy black hole
Recently, the image of a Schwarzschild black hole with an accretion disk has been revisited, and it showed that the “photon ring”, defined as highly bent light rays that intersect the disk plane more
The feature of shadow images and observed luminosity of the Bardeen black hole surrounded by different accretions
In this paper, by exploring the photon motion in the region near the Bardeen black hole, the shadow and observation properties of the black hole surrounded by various accretion models are studied.


Linearization stability of reflection-asymmetric thin-shell wormholes with double shadows
Wormholes are hypothetical objects which can be black hole mimickers with strong gravitational fields. Recently, Wielgus et al. have constructed reflection-asymmetric thin-shell wormholes which are
Reflection-asymmetric wormholes and their double shadows
We discuss construction and observational properties of wormholes obtained by connecting two Reissner-Nordstrom spacetimes with distinct mass and charge parameters. These objects are spherically
Structure and stability of traversable thin-shell wormholes in Palatini f(R) gravity
We study the structure and stability of traversable wormholes built as (spherically symmetric) thin shells in the context of Palatini f(R) gravity. Using a suitable junction formalism for these
Asymmetric thin-shell wormholes
Spacetime wormholes in isotropic spacetimes are represented traditionally by embedding diagrams which were symmetric paraboloids. This mirror symmetry, however, can be broken by considering different
Shadow images of Kerr-like wormholes
Investigations of shadows of astrophysical entities constitute a major source of insight into the evolution of compact objects. Such effects depend on the nature of the compact object and arise on
Wormhole Shadows
We propose a new method of detecting Ellis wormholes by use of the images of wormholes surrounded by optically thin dust. First, we derive steady solutions of dust and more general medium surrounding
Cosmological wormholes in f (R ) theories of gravity
Motivated by recent proposals of possible wormhole existence in galactic halos, we analyze the cosmological evolution of wormhole solutions in modified $f(R)$ gravity. We construct a dynamical
Shadows of rotating wormholes
The results obtained here indicate that, through the observations of their shadows, the wormholes which are considered in this work and have reasonable spin can be distinguished from a black hole.
Conformally symmetric traversable wormholes in modified teleparallel gravity
In this paper, we consider wormhole geometries in the context of teleparallel equivalent of general relativity (TEGR) as well as $f(T)$ gravity. The TEGR is an alternative geometrical formulation of
