Shadow of F(R)-EH Black Hole and Constraints from EHT Observations
Khadije Jafarzade, Saira Yasmin, Mubasher Jamil
This work investigates the optical properties of a static, spherically symmetric, electrically charged black hole in f(R) gravity coupled to Euler-Heisenberg(EH) nonlinear electrod…
Gravitational radiation reaction around a static black hole surrounded by a Dehnen type dark matter halo
Amjad Ashoorioon, Roberto Casadio, Khadije Jafarzade +2
We consider the motion of a particle in the geometry of a Schwarzschild-like black hole embedded in a dark matter (DM) halo with Dehnen type density profile and calculate the orbit…
Optical Signatures of Einstein-Euler-Heisenberg AdS/dS Black Holes in the light of Event Horizon Telescope
Khadije Jafarzade, Zeynab Bazyar, Sara Saghafi +1
Recent observations of the supermassive black holes and Sgr A by the Event Horizon Telescope (EHT) have sparked intensified interest in studying the optical appea…
Shadow Cast by the Kerr MOG Black Hole under the Influence of Plasma and Constraints from EHT Observations
Saira Yasmin, Khadije Jafarzade, Mubasher Jamil
The study of black hole (BH) shadows provide crucial insights into the nature of strong gravitational effects and the intricate structure of the spacetime surrounding BHs. In this…
Shadows and Optical Appearances of Black Holes in Gravity
Khadije Jafarzade, Sanjar Shaymatov, Mubasher Jamil
In this paper, we consider a charged AdS/dS black hole (BH) in gravity and study its optical features, including the shadow's geometrical shape and the energy emission rate…
Modelling the Sgr A and M87 shadows by using the Kerr-Taub-NUT metrics in the presence of a scalar field
khadije Jafarzade, Masoumeh Ghasemi-Nodehi, Fatemeh Sadeghi +1
The recent unveiling of the images of Sgr A* and M87* has significantly advanced our understanding of gravitational physics. In this study, we derive a class of Kerr-Taub-NUT metri…
A Study of Black Holes in ModMax Gravity: Gravitational Lensing and Constraints from EHT Observations
Khadije Jafarzade, Zeynab Bazyar, Mubasher Jamil
The study of astrophysical phenomena like black hole shadows is an effective approach to properly understand the modified gravity and explore its validity. Motivated by recent astr…
Kerr-Newman Black Holes in Weyl-Cartan Theory: Shadows and EHT constraints
Khadije Jafarzade, Seyed Hossein Hendi, Mubasher Jamil +1
With the recent release of the black hole image of Sgr A* alongside the earlier image of M87*, one can achieve an in-depth understanding of gravitational physics at the horizon sca…
Observational optical constraints of regular black holes
Khadije Jafarzade, Mahdi Kord Zangeneh, Francisco S. N. Lobo
In this work, we consider two recently introduced novel regular black hole solutions and investigate the circular null geodesics to find the connection between the photon sphere, t…
Shadow, deflection angle and quasinormal modes of Born-Infeld charged black holes
Khadije Jafarzade, Mahdi Kord Zangeneh, Francisco S. N. Lobo
In this paper, we consider black holes in the consistent Aoki-Gorji-Mukohyama theory of the four-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity in the presence of Born-Infeld (…
Optical features of AdS black holes in the novel 4D Einstein-Gauss-Bonnet gravity coupled to nonlinear electrodynamics
Khadije Jafarzade, Mahdi Kord Zangeneh, Francisco S. N. Lobo
An alternative theory of gravity that has attracted much attention recently is the novel four-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity. The theory is rescaled by the Gaus…
