Kerr-like black holes shadow surrounded by dark matter halos: Comparison between various dark matter profiles
Malihe Heydari-Fard, Mohaddese Heydari-Fard
The study of shadows of static and rotating black holes immersed in various dark matter halo profiles has gained significant attention in recent years. In this paper, we consider t…
Rotating black holes in the Hernquist galactic halo and its accretion disk luminosity
Malihe Heydari-Fard, Mohaddese Heydari-Fard
Static, spherically symmetric black holes immersed in a dark matter halo with a Hernquist-type density profile have been derived by Cardoso et. al. in Ref. \redcite{Cardoso:2021wlq…
Influence of plasma on the observational appearance of rotating black holes in Horndeski gravity
Malihe Heydari-Fard, Mohaddese Heydari-Fard
Exploring the influence of plasma on the light rays trajectories in the vicinity of black holes is significat since that astrophysical black holes are generally surrounded by a pla…
Galactic black hole immersed in a dark halo with its surrounding thin accretion disk
Mohaddese Heydari-Fard, Malihe Heydari-Fard, Nematollah Riazi
By considering the analytic, static and spherically symmetric solution for the Schwarzschild black holes immersed in dark matter fluid with non-zero tangential pressure \cite{Jusuf…
Thin accretion disk images of rotating hairy Horndeski black holes
Mohaddese Heydari-Fard, Malihe Heydari-Fard, Nematollah Riazi
By considering the steady-state Novikov-Thorne model, we study thin accretion disk processes for rotating hairy black holes in the framework of the Horndeski gravity. We obtain the…
On null geodesics and shadow of hairy black holes in Einstein-Maxwell-dilaton gravity
Mohaddese Heydari-Fard, Malihe Heydari-Fard, Hamid Reza Sepangi
The time-like and null-like geodesics around compact objects are some of the best tools to classify and understand the structure of a space-time. In this paper, we study the null g…
Null geodesics and shadow of 4 Einstein-Gauss-Bonnet black holes surrounded by quintessence
Malihe Heydari-Fard, Mohaddese Heydari-Fard
We study the properties of the null geodesics of four-dimensional Einstein-Gauss-Bonnet black holes surrounded by quintessence matter. Due to the quintessence correction, we discus…
Thin accretion disks around rotating black holes in Einstein-Gauss-Bonnet gravity
Mohaddese Heydari-Fard, Malihe Heydari-Fard, Hamid Reza Sepangi
Recently, Kumar and Ghosh have derived Kerr-like rotating black hole solutions in the framework of four-dimensional Einstein-Gauss-Bonnet theory of gravity and investigated the bla…
Thin accretion disk signatures of scalarized black holes in Einstein-scalar-Gauss-Bonnet gravity
Mohaddese Heydari-Fard, Hamid Reza Sepangi
Einstein-scalar-Gauss-Bonnet gravity has recently been known to exhibit spontaneous scalarization. In the presence of the Gauss-Bonnet term the no-hair theorem can be evaded and no…
Bending of light in novel 4 Gauss-Bonnet-de Sitter black holes by Rindler-Ishak method
Mohaddese Heydari-Fard, Malihe Heydari-Fard, H. R. Sepangi
We study the bending of light in the space-time of black holes in four-dimensional Einstein-Gauss-Bonnet theory of gravity, recently proposed by Glavan and Lin \cite{Glavan}. Using…
Higher-order geodesic deviations and orbital precession in a Kerr-Newman space-time
Mohaddese Heydari-Fard, Malihe Heydari-Fard, Hamid Reza Sepangi
A novel approximation method in studying the perihelion precession and planetary orbits in general relativity is to use geodesic deviation equations of first and high-orders, propo…
Generalized virial theorem in warped DGP brane-world
Malihe Heydari-Fard, Mohaddese Heydari-Fard
We generalize the virial theorem to the warped DGP brane world scenario and consider its implications on the virail mass. In this theory the four dimensional scalar curvature term…
Virial mass in warped DGP-inspired L(R) gravity
Malihe Heydari-Fard, Mohaddese Heydari-Fard
A version of the virial theorem is derived in a brane-world scenario in the framework of a warped DGP model where the action on the brane is an arbitrary function of the Ricci scal…
