摘要

In the present paper, the characterization of the Kerr metric found by Marc Mars is extended to the Kerr-Newman family. A simultaneous alignment of the Maxwell field, the Ernst two-form of the pseudo-stationary Killing vector field, and the Weyl curvature of the metric is shown to imply that the space-time is locally isometric to domains in the Kerr-Newman metric. The paper also presents an extension of Ionescu and Klainerman's null tetrad formalism to explicitly include Ricci curvature terms.

Analysis of the wave functions for accelerating Kerr-Newman metric

Yi-Gu Chen, Hai-Bo Wei, Hui Zheng, Zai-Dong Wang, Zhong-Heng Li

Summary: This paper explores wave equations describing massless fields of spins s ≤ 2 in accelerating Kerr-Newman black holes, finding that they can be written as a compact master equation that can be separated into radial and angular equations. The solutions are shown to have analytical solutions and approximate solutions for the radial equation. The results demonstrate the possibility of studying similarities between gravitational waves and other massless spin fields, with potential applications in astrophysics such as quasinormal modes, scattering, and stability.

Hawking radiation particle spectrum of a Kerr-Newman black hole

Joshua Foo, Michael R. R. Good

Summary: This paper examines a simplified model for Hawking radiation produced by Kerr-Newman black holes, deriving the particle spectrum of the outgoing massless, scalar field and its thermal distribution. It also calculates the particle spectrum of the extremal Kerr-Newman system, demonstrating that the total emitted energy is finite.

New form of the Kerr-Newman solution

M. P. Hobson

Summary: A new form of the Kerr-Newman solution is discussed, which uses a time coordinate to represent the proper time for a charged massive particle released from rest at infinity. The chosen coordinates ensure the well-behaved behavior of the solution at horizons and provide an intuitive description of various physical phenomena.

Gravitational time delay effects by Kerr and Kerr-Newman black holes in strong field limits

Tien Hsieh, Da-Shin Lee, Chi-Yong Lin

Summary: This study focuses on the time delay between relativistic images caused by the gravitational lensing of Kerr and Kerr-Newman black holes, finding potential correlations between mass, spin, and time delay. The charge of the black hole enhances time delay between images on opposite sides of the optical axis, while reducing the delay when both images are on the same side. Observations of time delay due to galactic and supermassive black holes are also examined.

Strong gravitational lensing by Kerr and Kerr-Newman black holes

Tien Hsieh, Da-Shin Lee, Chi-Yong Lin

Summary: The study focuses on strong gravitational lensing caused by Kerr and Kerr-Newman black holes, deriving analytical expressions for deflection angles. It is found that an increase in the black holes' angular momentum and charge leads to an increase in the angular separation of relativistic images. The potential observability of these relativistic images due to the effects of angular momentum and charge will be discussed.

The Superluminal Phenomenon of Light Near the Kerr-Newman Black Hole or Super-Gravitational Source

Ting-Hang Pei

Summary: In this study, the Kerr-Newman metric based on the theory of general relativity is used to discuss the potential of observing superluminal phenomenon of light near a black hole. The results show that the rotational term a and the charge term R-Q are closely related to the maximum speed of light and the range of the superluminal phenomenon. The study highlights that the superluminal phenomenon for light may be observable in cases where the radial velocity component is dominant, with the other two components being comparatively small.

Evolution of braneworld Kerr-Newman naked singularities

Martin Blaschke, Zdenek Stuchlik, Sudipta Hensh

Summary: We study the evolution of the braneworld Kerr-Newman (K-N) naked singularities with a focus on the influence of tidal charge. We find that counterrotating accretion transforms a K-N naked singularity into an extreme black hole, while corotating accretion leads to various outcomes. Notably, a low-spin naked singularity with a dimensionless tidal charge less than 0.25 can be converted into an extreme black hole, whereas other cases result in transcendent states.

Magnetized Kerr-Newman-Taub-NUT spacetimes

Masoud Ghezelbash, Haryanto M. Siahaan

Summary: A new class of exact solutions in the Einstein-Maxwell theory was discovered by applying the Ernst magnetization process to Kerr-Newman-Taub-NUT spacetimes. The solutions were found to be regular everywhere, and quasilocal conserved quantities, the corresponding Smarr formula, and the first law of thermodynamics were also identified for these spacetimes.

Thermodynamics of two aligned Kerr-Newman black holes

H. Garcia-Compean, V. S. Manko, C. J. Ramirez-Valdez

Summary: Using the concept of thermodynamic length, the first law of thermodynamics for two equal mass Kerr-Newman black holes separated by a massless strut was consistently derived. The expression of the free energy for two generic Kerr-Newman black holes was also proposed in this study.

Conditions for superradiant instability of the Kerr-Newman black holes

Yun Soo Myung

Summary: The conditions for superradiant instability of Kerr-Newman black holes under a charged massive scalar perturbation are found by analyzing the asymptotic scalar potential and far-region wave function. It is also discovered that the conditions for superradiant stability of Kerr-Newman black holes correspond to the absence of a trapping well. The analysis is applied to Kerr black holes to find a condition for superradiant instability.

Equatorially symmetric configurations of two Kerr-Newman black holes

V. S. Manko, E. Ruiz

Summary: In this paper, two physically meaningful configurations of a pair of equal Kerr-Newman corotating black holes separated by a massless strut are elaborated using the general equatorially symmetric two-soliton solution. The thermodynamic properties of these binary configurations are studied and the first law of thermodynamics taking correctly into account the magnetic field contribution is formulated for each case.

Curvature induced scalarization of Kerr-Newman black hole spacetimes

Ming Zhang, Jie Jiang

Summary: In the extended scalar-tensor-Gauss-Bonnet (ESTGB) field theory, a specific nonminimal coupling between a massless scalar field and the Gauss-Bonnet curvature invariant promotes the tachyonic instability of the Kerr-Newman (KN) black hole. The critical spin and charge for the onset of the spontaneous scalarization phenomenon in the KN black hole are calculated under the infinitely large coupling limit. Furthermore, an analytical formula for the coupling-strength-dependent critical existence line is obtained for the black-hole-scalar-field configuration in the finite large coupling regime. Numerical methods are used to plot threshold curves between bald KN black holes and their hairy counterparts. Interestingly, scalarization of the KN black hole is found to occur in the vanishing spin limit in the ESTGB theory.

Entropy of Kerr-Newman-AdS black holes with torsion

M. Blagojevic, B. Cvetkovic

Summary: The canonical approach to black hole entropy in Poincaré gauge theory is extended to include the Maxwell field as a matter source. The new formalism is used to calculate asymptotic charges and entropy of Kerr-Newmann-AdS black holes with torsion. The result suggests that the first law, with a nontrivial contribution of the Maxwell field, takes the same form as in general relativity.

Kerr-Newman-Jacobi geometry and the deflection of charged massive particles

Zonghai Li, Junji Jia

Summary: This paper investigates the deflection of a charged particle in the equatorial plane of Kerr-Newman spacetime using the Jacobi geometry method. The results show that the spin of the black hole plays a significant role in influencing the deflection angle of the particles, causing it to decrease or increase under certain conditions.

On the discrete version of the Kerr-Newman solution

V. M. Khatsymovsky

Summary: This paper continues the study of black holes in the Regge calculus framework, focusing on the discrete Kerr-Newman-type solution. By integrating over the connection, the classical solution with a certain edge length scale emerges as an optimal starting point for perturbative expansion. The paper investigates the electromagnetic contribution to the metric and curvature on the singularity ring, finding that it is infinitely greater than the contribution of the delta-function-like mass distribution.
