Black Hole Physics in Modified Gravity Theories

A reliable gravitational model describing the universe and black hole physics depends on its compatibility with the observational data. From the cosmological point of view, even though Einstein's theory of relativity describes the evolution of the cosmos quite well, it suffers some defects in explaining some phenomena, such as the galaxy rotation curves, accelerated expansion of the universe, and Hubble tension.

From the astrophysical point of view, we can refer to the essential singularity located at the center of the black holes, among others. Although the properties of spacetime outside the event horizon are described by a handful of parameters characterizing the black hole conserved charges, the curvature singularity at the core of black holes remained a crucial and outstanding problem. In this context, plenty of efforts have been made to address this issue, such as assigning conformal symmetry to spacetime, employing nonlinear electrodynamic fields, and considering quantum corrections to general relativistic theories.

The incapability of Einstein's theory of relativity in describing these phenomena can be due to shortcomings in either the gravitational theory or the matter source. Hence, these defects in general relativity motivate one to invent and develop gravitational theories beyond general relativity and/or take into account various matter fields as other possibilities to describe black hole physics and the universe.

In this Research Topic, we aim to collect manuscripts and review articles from leading experts prepared based on modified gravity theories of general relativity and developed in the contexts of black hole physics and cosmology with original contributions.

For instance, the Research Topic covers the following topics in modified gravity:

• Gravitational waves.
• Modified gravity models.
• Anti-de Sitter/conformal field theory (AdS/CFT) correspondence.
• Nonlinear electrodynamics.
• Black hole thermodynamics.
• Geometrical thermodynamics.
• Quantum corrected black holes.
• Black hole and wormhole solutions.
• Relativistic astrophysics and accretion disks.
• Relativistic kinetic theory on curved spacetime.
• Black hole perturbation theory and quasinormal modes.
• Regular black holes.
