چکیده
Abstract We analysed the shadow cast by charged rotating black hole (BH) in presence of perfect fluid dark matter (PFDM). studied null geodesic equations and obtained BH to see effects PFDM parameter ? , charge Q rotation a it is noticed that size as well shape affected due parameter, parameter. Thus, seen around affects its spacetime. also investigated influence all parameters (PFDM BHs rotational ) on effective potential, energy emission graphical representation, compare results with non case usual general relativity. To this end, we have explored effect deflection angle Einstein rings.

Black holes surrounded by uniformly rotating rings
Black Holes have grown to become a well accepted member of the canon of astrophysical objects. Nonetheless, there is still very little known about spacetimes containing both matter and Black Holes. But for a few exceptions (e.g. the Oppenheimer-Snyder collapse), such situations have been considered using approximation methods, perturbation techniques or pioneering, but still somewhat inaccurate...
متن کاملBlack Hole Remnants and Dark Matter
We argue that, when the gravity effect is included, the generalized uncertainty principle (GUP) may prevent black holes from total evaporation in a similar way that the standard uncertainty principle prevents the hydrogen atom from total collapse. Specifically we invoke the GUP to obtain a modified Hawking temperature, which indicates that there should exist non-radiating remnants (BHR) of abou...
متن کاملComplex Instantons and Charged Rotating Black Hole Pair Creation
We consider the general process of pair-creation of charged rotating black holes. We find that instantons which describe this process are necessarily complex due to regularity requirements. However their associated probabilities are real, and fully consistent with the interpretation that the entropy of a charged rotating black hole is the logarithm of the number of its quantum states. Black hol...
متن کاملMass inflation in a rotating charged black hole.
The structure of the Cauchy horizon of a charged rotating black hole is analyzed under the combined effect of an ingoing and outgoing flux of gravitational waves. In particular, by means of an axisymmetric realization of the Ori model, the growth of the mass parameter near the Cauchy horizon is studied in the slow rotation approximation. It is shown that the mass-parameter inflates, while the a...
متن کاملRotating charged black hole solution in heterotic string theory.
We construct a solution of the classical equations of motion arising in the low energy effective field theory for heterotic string theory. This solution describes a black hole in four dimensions carrying mass M , charge Q and angular momentum J . The extremal limit of the solution is discussed.
