Kerr black hole in presence of force-free magnetic field
Haidar Sheikhahmadi
We extend the study of force-free magnetospheres from non-rotating to rotating black holes \cite{Sheikhahmadi} and investigate the influence of a force-free magnetic field on the g…
Black hole solutions to Einstein-Bel-Robinson gravity
S. N. Sajadi, Robert B. Mann, H. Sheikhahmadi +1
In this paper, we study the physical properties of black holes in the framework of the recently proposed Einstien-Bel-Robinson gravity. We show that interestingly the theory propag…
Vacuum Zero Point Energy and its Statistical Correlations in dS Background
Hassan Firouzjahi, Haidar Sheikhahmadi
We study the vacuum zero point energy associated to a scalar field with an arbitrary mass and conformal coupling in a dS background. Employing dimensional regularization scheme, we…
Astrophysical and electromagnetic emissivity properties of black holes surrounded by a quintessence type exotic fluid in the Scalar-Vector-Tensor Modified Gravity
Haidar Sheikhahmadi, Saheb Soroushfar, S. N. Sajadi +1
The astrophysical consequences of the presence of a quintessence scalar field on the evolution of the horizon and on the accretion disk surrounding a static black hole, in the Scal…
