Summary: In this paper, we investigate the 4D Einstein-Gauss-Bonnet black hole and its thermodynamics. The study includes the analysis of three different asymptotic spacetimes and the correlation between emission modes and temperature. The results show interesting behaviors of temperature and emission in different spacetime backgrounds.

Summary: This study investigates Hawking radiation in higher dimensional Reissner-Nordstrom black holes received by an observer at infinity. The frequency-dependent transmission rates are evaluated numerically, showing sensitivity to spacetime dimension and a practical vanishing of the transmission coefficient near zero frequency.

Summary: This study investigates quantum gravity corrections to the thermodynamic quantities of Reissner-Nordstrom anti-de Sitter black hole surrounded by quintessence under the GUP effect. The findings suggest higher efficiency under the GUP effect compared to the standard one, especially when considering the attractive Coulomb interaction and influence of zitterbewegung particles.

Summary: In this study, we analytically investigate the scalarization of higher-dimensional charged Reissner-Nordstrom black hole. It is found that a static massive scalar field, which is non-minimally coupled to the Gauss-Bonnet invariant, can be supported by the higher-dimensional black hole in the super-critical charge regime. Moreover, we demonstrate that the static massive scalar shell can be incredibly thin in the large mass regime.

Summary: The Hawking temperature and Entropy of Reissner-Nordstrom (RN) black hole can be derived from energy quantization of test particles moving around different circular orbits, similar to Bohr's atomic model. Energy transitions may lead to detectable radiations in the future. By using gravitoelectromagnetism, it is possible to split the upper bound of energy without considering the quantization effects on energy level splitting, due to the hypothetical nature of gravitipole.

Summary: This study investigates the gravitational bending of acoustic Schwarzschild black hole and carefully analyzes the gravitational deflection angle of particles, weak gravitational lensing, and Einstein ring. The results show that gravitational bending effect is enhanced in acoustic Schwarzschild black hole compared to conventional Schwarzschild black hole, indicating that acoustic black holes may be more easily detectable in gravitational bending effects and weak gravitational lensing observations.

Summary: Research suggests that overcharging a charged Taub-NUT regular black hole is possible through the scattering of a charged field and absorption of a charged particle. Both near-extremal and extremal black holes cannot be overcharged through charged scalar field scattering. While the event horizon of a near-extremal charged Taub-NUT regular black hole may be destroyed by absorption of a charged particle, it may not be overcharged if charge and energy cross the event horizon in a continuous path.

Summary: The entropy calculations for black holes with two horizons, such as the Reissner-Nordstrom black hole and the Kerr black hole, show that the entropy is not determined by the area of the outer horizon but by the correlations between the two horizons. The entropy depends only on the mass M of the black hole and is independent of the black hole charge Q.

Summary: This study focuses on understanding the thermal equilibrium of large black holes with toroidal topology in anti-de Sitter spacetimes through a simple model. It shows that it is possible for a large toroidal black hole to evolve into a small but stable one through Hawking evaporation.

Summary: This article investigates the dynamics of neutral and charged particles in a magnetic field around a Reissner-Nordstrom black hole surrounded by quintessence, considering Noether symmetries and conservation laws in the corresponding spacetime. The study explores the effects of angular momentum, quintessence parameter, and magnetic field on the particles' dynamics, and also examines the orbit stability of the spacetime using the Lyapunov exponent.

Summary: In this study, the tunneling radiation characteristics of fermions and bosons in Vaidya-Bonner de Sitter black hole space-time were corrected by considering Lorentz symmetry breaking theory. The new modified forms of Dirac equation for fermions with spin 1/2 and Klein-Gordon equation for bosons in the curved space-time of the black hole were obtained. Through solving these equations, new and corrected expressions for surface gravity, Hawking temperature, and tunneling rate of the black hole were obtained and discussed.

Summary: The paper presents a novel solution describing magnetized spacetime outside an electrically charged object with NUT parameter. The solution is obtained by applying Ernst magnetization to the Reissner-Nordstrom-Taub-NUT spacetime as a seed. After discussing some physical aspects, it is shown that the extremal entropy of a magnetized Reissner-Nordstrom-Taub-NUT black hole can be reproduced using the Cardy formula.

Summary: In this paper, the quantum correction on the thermodynamics of the Reissner-Nordstrom black hole in the presence of quintessence matter associated with dark energy is investigated. The modified Hawking temperature, heat capacity, and entropy functions of the black hole are derived. It is found that the modified uncertainty principles and normalization factor have significant effects on the thermodynamic properties of the black hole, and graphical methods are used to compare the findings within different uncertainty principles.

Summary: This study discusses the thermodynamic properties of Reissner-Nordstrom-de Sitter (RN-dS) space-time and finds that the coexistent curve of Hawking-Page temperature and pressure is a closed curve with upper bounds. This has significant implications for understanding the evolution and microstructure of de Sitter space-time.

Summary: In this study, the thermal stability of a charged non-rotating black hole is examined, revealing that it is quasi stable but not completely stable, contrary to Hawking's prediction. The black hole exhibits phase transition and attempts to resist decay under Hawking radiation, without ultimate success.
