About this Research Topic
Hawking radiation has become one of the dominant problems in black hole physics. By using a different technique to describe the Hawking radiation, the field equation without a singularity is used to study the radiation phenomenon and dynamic spacetime even within the event horizon of different geometries of black holes with mass, rotation, acceleration charged, the cosmological constant, Rastall parameter, coupling parameter, gauge potential, etc. The two important things to understand about BH geometry are shadows and Hawking radiation.
We can investigate the tunneling radiation and shadows by means of various approaches. The Editors of this Research Topic invite the submissions of papers that cover one of the following areas:
[1] Theoretical, mathematical, and observational approaches to studying tunneling radiation in black holes
[2] Computational and numerical techniques and simulations for the existence of black holes radiation
[3] Novel development and refinement of relevant mathematical protocols for tunneling radiation from a black hole
[4] The significance of additional resources in existing literature related to Hawking temperature and black hole shadow
[5] Novel studies based on theoretical, observational, or numerical methods on particular issues related to Hawking temperature and its shadow
[6] Mathematical support and validation of previously published theoretical models related to tunneling radiation and shadows as well as deflection angle.
In this Research Topic, aspects of the large-scale structure of black hole deflection angle and black hole radiation will be explored in the framework of different spacetime and alternative models, including models dealing with changing fundamental parameters and more fundamental considerations such as those on deflection angle, shadow, and black hole emission.
