“…Tunneling of particles from black holes and the resulting Hawking radiation have been studied for scalars, [ 105–114 ] fermions [ 115–122 ] and vectors. [ 123–129 ] Tunneling offers more than just a valuable method to verify the thermodynamic properties of black holes in that it also serves as an alternative conceptual approach to grasp the fundamental physical process behind black hole radiation. In general, tunneling methods involve the computation of the imaginary part of the action associated with the classically forbidden process of s‐wave emission across the black hole horizon.…”

Symmergent gravity is an emergent gravity model with an curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of ). With variable scalar curvature, however, asymptotically‐flat symmergent black hole solutions turn out to explicitly depend on the quadratic curvature term. In the present work, asymptotically‐flat symmergent black holes with variable scalar curvature are constructed and used its evaporation, shadow, and deflection angle to constrain the symmergent gravity parameters. Concerning their evaporation, new particles predicted by symmergent gravity are found, even if they do not interact with the known particles, can enhance the black hole evaporation rate. Concerning their shadow, statistically significant symmergent effects are reached at the level for the observational data of the Event Horizon Telescope (EHT) on the Sagittarius A* supermassive black hole are shown. Concerning their weak deflection angle, discernible features for the boson‐fermion number differences are revealed, particularly at large impact parameters. These findings hold the potential to serve as theoretical predictions for future observations and investigations on black hole properties.

This article investigates the influence of the Generalized Uncertainty Principle (GUP) on the emission of Hawking quanta in a rotating linear dilaton black hole spacetime. The study proposes a GUP-reinforced black hole thermal emission model that takes into account the quantum tunneling process with GUP effects. The result obtained for the corrected temperature suggests that temperature of the GUP-reinforced Hawking radiation decreases with the increasing GUP parameter and gets higher values with the increasing mass of the black hole. The study also discusses the implications of these findings on the corrected entropy and hence the information loss paradox, and the potential for experimental verification of GUP effects in astrophysical observations. Overall, this work highlights the significant role of GUP in the thermal emission of non-asymptotically flat stationary black holes and can shed light on the intricate interplay between quantum gravity and astrophysics.

“…These corrections make the radiation cease at some particular Hawking temperature, leaving the remnant mass. When this consideration holds, the temperature stops rising [59] (M − dM)(1 + 𝛼℘) ≈ M (42) where 𝜔 = dM, 𝛼 0 ( 1 M Planks ) = 𝛼, and M Planks = 𝜔. Here, 𝛼 0 and M Planks are represent the dimensionless parameter and Planck mass and quantum gravity effects for 𝛼 0 < 10 5 in refs.…”

This work analyzes the Einstein-Gauss-Bonnet gravity of charged black hole solutions through Newman-Janis approach. The Hawking temperature for corresponding black hole is also computed. The solution depends upon rotation parameter a, black hole mass, charge and horizon. Moreover, the graphical behavior of temperature via event horizon to analyze the stability of black hole under the effects of rotation parameter is discussed. The graphs are plotted in the presence/absence of rotation parameter and charge. Furthermore, the Hawking temperature under gravity effects is studied by using the semi-classical method. It is also observed that the maximum temperature at non-zero horizon depicts the BH remnant. Finally, the logarithmic corrected entropy for given black hole is computed and the logarithmic corrected entropy under effects of rotation and correction parameter are studied.
