Relativistic rotation curve for cosmological structures
Mohammadhosein Razbin, Javad T. Firouzjaee, Reza Mansouri
Using a general relativistic exact model for spherical structures in a cosmological background, we have put forward an algorithm to calculate the test particle geodesics within suc…
A concrete anti-de Sitter black hole with dynamical horizon having toroidal cross-sections and its characteristics
Pouria Dadras, J. T. Firouzjaee, Reza Mansouri
We propose a special solution of Einstein equations in the general Vaidya form representing a dynamical black hole having horizon cross-sections with toroidal topology. The concret…
Conformally rescaled spacetimes and Hawking radiation
Alex B. Nielsen, J. T. Firouzjaee
We study various derivations of Hawking radiation in conformally rescaled metrics. We focus on two important properties, the location of the horizon under a conformal transformatio…
