Ergosphere and shadow of a rotating regular black hole
Sushant G. Ghosh, Muhammed Amir, Sunil D. Maharaj
The spacetime singularities in classical general relativity predicted by the celebrated singularity theorems are formed at the end of gravitational collapse. Quantum gravity is the…
Quasinormal modes, shadow and greybody factors of 5D electrically charged Bardeen black holes
Kimet Jusufi, Muhammed Amir, Md Sabir Ali +1
We study quasinormal modes (QNMs) in 5D electrically charged Bardeen black holes spacetime by considering the scalar and electromagnetic field perturbations. The black holes spacet…
Rotating five-dimensional electrically charged Bardeen regular black holes
Muhammed Amir, Md Sabir Ali, Sunil D. Maharaj
We derive a rotating counterpart of the five-dimensional electrically charged Bardeen regular black holes spacetime by employing the Giampieri algorithm on static one. The associat…
Shadow of rotating charged black hole with Weyl corrections
Md Sabir Ali, Muhammed Amir
We construct theoretical investigation of the black hole shadow for rotating charged black hole in an asymptotically flat, axisymmetric, and stationary spacetime with Weyl correcti…
Distinguishing rotating naked singularities from Kerr-like wormholes by their deflection angles of massive particles
Kimet Jusufi, Ayan Banerjee, Galin Gyulchev +1
We study the gravitational deflection of relativistic massive particles by Janis-Newman-Winicour (JNW) spacetimes (also known as a rotating source with a surface-like naked singula…
Shadow images of Kerr-like wormholes
Muhammed Amir, Kimet Jusufi, Ayan Banerjee +1
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 obj…
Particle acceleration of two general particles in the background of rotating Ayón-Beato-García black holes
Fazlay Ahmed, Muhammed Amir, Sushant G. Ghosh
The rotating Ayón-Beato-García (ABG) black holes, apart from mass () and rotation parameter (), has an additional charge and encompassed the Kerr black hole as particular…
Shadow of charged wormholes in Einstein-Maxwell-dilaton theory
Muhammed Amir, Ayan Banerjee, Sunil D. Maharaj
The study of shadow is quite prominent nowadays because of the ongoing Event Horizon Telescope\footnote{https://eventhorizontelescope.org/} observations. We construct the shadow im…
Shadows of rotating five-dimensional charged EMCS black holes
Muhammed Amir, Balendra Pratap Singh, Sushant G. Ghosh
Higher dimensional theories admit astrophysical objects like supermassive black holes, which are rather different from standard ones, and their gravitational lensing features devia…
Quintessence background for Einstein-Gauss-Bonnet black holes
Sushant G. Ghosh, Muhammed Amir, Sunil D. Maharaj
As we know that the Lovelock theory is an extension of the general relativity to the higher-dimensions, in this theory the first and the second order terms correspond to the genera…
Collision of two general particles around a rotating regular Hayward's black holes
Muhammed Amir, Fazlay Ahmed, Sushant G. Ghosh
The rotating regular Hayward's spacetime, apart from mass () and angular momentum (), has an additional deviation parameter () due to the magnetic charge, which generalize…
Shadow of rotating regular black holes
Ahmadjon Abdujabbarov, Muhammed Amir, Bobomurat Ahmedov +1
We study the shadows cast by the different types of rotating regular black holes viz. Ayón-Beato-García {(ABG)}, Hayward, and Bardeen. These black holes have in addition to the tot…
Shapes of rotating nonsingular black hole shadows
Muhammed Amir, Sushant G. Ghosh
It is believed that curvature singularities are a creation of general relativity and hence, in the absence of a quantum gravity, models of nonsingular black holes have received sig…
Horizon structure of rotating Bardeen black hole and particle acceleration
Sushant G. Ghosh, Muhammed Amir
We investigate the horizon structure and ergosphere in a rotating Bardeen regular black hole, which has an additional parameter () due to magnetic charge, apart from mass ()…
Rotating Hayward's regular black hole as particle accelerator
Muhammed Amir, Sushant G. Ghosh
Recently, Banãdos, Silk and West (BSW) demonstrated that the extremal Kerr black hole can act as a particle accelerator with arbitrarily high center-of-mass energy () when…
Rotating Ayón-Beato-García black hole as a particle accelerator
Sushant G. Ghosh, Pankaj Sheoran, Muhammed Amir
We study the collision of two particles with equal masses moving in the equatorial plane near horizon of the rotating regular Ayón-Beato-García (ABG) black hole (BH) and calculate…
