Black hole shadow of a rotating scale-dependent black hole [PDF]

open access: yesPhysical Review D, 2020
In this work, starting from a spherically symmetric scale--dependent black hole, a rotating solution is obtained by following the Newman--Janis algorithm without complexification. Besides studying the horizon, the static conditions and causality issues of the rotating solution, we get and discuss the shape of its shadow.

Entropy bound of horizons for charged and rotating black holes

open access: yesPhysics Letters B, 2015
We revisit the entropy product, entropy sum and other thermodynamic relations of charged and rotating black holes. Based on these relations, we derive the entropy (area) bound for both event horizon and Cauchy horizon.

Applications of Thermodynamic Geometries to Conformal Regular Black Holes: A Comparative Study

open access: yesUniverse, 2023
In this paper, we investigate the thermal stability and thermodynamic geometries of non-rotating/rotating charged black holes. For these black holes, we apply barrow entropy to determine the physical quantities such as mass and temperature of the system ...

ROTATING BRANEWORLD BLACK HOLES [PDF]

open access: yesThe Eleventh Marcel Grossmann Meeting, 2008
We present a Kerr-Newman type stationary and axisymmetric solution that describes rotating black holes with a tidal charge in the Randall-Sundrum braneworld. The tidal charge appears as an imprint of nonlocal gravitational effects from the bulk space.

Rotating Kaluza–Klein black holes [PDF]

open access: yesNuclear Physics B, 2000
All regular four-dimensional black holes are constructed in the theory obtained by Kaluza-Klein reduction of five-dimensional Einstein gravity. They are interpreted in string theory as rotating bound states of D0- and D6-branes. Conservation of angular momentum is important for the stability of the bound states.

Regular Rotating Black Holes

open access: yes, 2023
The collapse of astrophysically significant bodies generates, under suitable conditions, black holes. Since one expects the generator of the black hole to be a rotating body, the black hole will also rotate. The existence of inner singularities in classical solutions for rotating black holes and the fact that General Relativity is incompatible with ...

Holographic probes of inner horizons

open access: yesJournal of High Energy Physics, 2020
We study the inner horizons of rotating and charged black holes in anti-de Sitter space. These black holes have a classical analytic extension through the inner horizon to additional asymptotic regions.

Rotating spacetimes generalizing Lifshitz black holes [PDF]

open access: yesThe European Physical Journal C, 2021
AbstractWe present a spinning black hole solution in d dimensions with a maximal number of rotation parameters in the context of the Einstein–Maxwell-Dilaton theory. An interesting feature of such a solution is that it accommodates Lifshitz black holes when the rotation parameters are set to zero.

Counter-rotating black holes from FRII lifetimes

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Estimates suggest that while FRII jets appear to have lifetimes constrained to hundreds of millions of years, radio galaxies with FRI jets appear to be longer lived.
