We investigate strong field gravitational lensing by rotating Simpson-Visser black hole, which has an additional parameter (0 ≤ l/2M ≤ 1), apart from mass (M) and rotation parameter (a). A rotating Simpson-Visser metric correspond to (i) a Schwarzschild metric for l/2M = a/2M = 0 and M ≠ 0, (ii) a Kerr metric for l/2M = 0, |a/2M| < 0.5 and M ≠ 0 (iii) a rotating regular black hole metric for |a/2M| < 0.5, M ≠ 0 and l/2M in the range 0 < l/2M < 0.5 + √((0.5)2-(a/2M)2), and (iv) a traversable… 

Trapping horizons of the evolving charged wormhole and black bounce

We obtain one family of dynamic solutions in the Einstein-Maxwell-scalar(EMS) theory. Our solutions could describe the evolving charged black(white) hole or wormhole and its transition, including the

Testing Kerr black hole mimickers with quasi-periodic oscillations from GRO J1655-40

The measurements of quasi-periodic oscillations (QPOs) provide a quite powerful tool to test the nature of astrophysical black hole candidates in the strong gravitational field regime. In this paper,

Testing black hole mimickers with the Event Horizon Telescope image of Sagittarius A$^*$

The Event Horizon Telescope (EHT) has recently observed the image and shadow of the supermassive compact object Sagittarius A ∗ (Sgr A ∗ ). According to the EHT collaboration, the observed image is

Simpson and Visser recently proposed a phenomenological way to avoid some kinds of space-time singularities by replacing a parameter whose zero value corresponds to a singularity (say, r ) with the

Analytical study of gravitational lensing in Kerr-Newman black-bounce spacetime

We investigate the equatorial deflection angle of light rays propagating in Kerr-Newman black-bounce spacetime. Furthermore, we analyze the light ray trajectories and derive a closed-form formula for

Black bounces, wormholes, and partly phantom scalar fields

Simpson and Visser recently proposed a phenomenological way to avoid some kinds of space-time singularities by replacing a parameter whose zero value corresponds to a singularity (say, r ) with the

Constraining a modified gravity theory in strong gravitational lensing and black hole shadow observations

We study the strong gravitational lensing effect around rotating black holes in different gravity theories. By calculating the deflection angle of strong gravitational lensing, we evaluate the lensing

Testing regular black holes with X-ray and GW data

. The presence of spacetime singularities in physically relevant solutions of the Einstein Equations is normally interpreted as a symptom of the breakdown of classical general relativity at very high

—Gravitational lensing is the relativistic effect gener- ated by massive bodies, which bend the space-time surrounding them. It is a deeply investigated topic in astrophysics and allows validating

Gravitational lensing by black holes with multiple photon spheres

We study gravitational lensing of light by hairy black holes, which, in a certain parameter regime, can possess two photon spheres of different size outside the event horizon. In particular, we focus

Novel black-bounce spacetimes: Wormholes, regularity, energy conditions, and causal structure

We develop a number of novel "black-bounce" spacetimes. These are specific regular black holes where the "area radius" always remains non-zero, thereby leading to a "throat" that is either timelike

Photon ring structure of rotating regular black holes and no-horizon spacetimes

The Kerr black holes possess a photon region with prograde and retrograde orbits radii, respectively, M⩽rp−⩽3M and 3M⩽rp+⩽4M , and thereby always cast a closed photon ring or a shadow silhouette for

Particle acceleration around rotating Einstein-Born-Infeld black hole and plasma effect on gravitational lensing

We consider a time-like geodesics in the background of rotating Einstein-Born-Infeld (EBI) black hole to examine the horizon and ergosphere structure. The effective potential that governs the

From a locality-principle for new physics to image features of regular spinning black holes with disks

Current observations present unprecedented opportunities to probe the true nature of black holes, which must harbor new physics beyond General Relativity to provide singularity-free descriptions. To

Image features of spinning regular black holes based on a locality principle

To understand the true nature of black holes, fundamental theoretical developments should be linked all the way to observational features of black holes in their natural astrophysical environments.
