Universal thermodynamic topological classes of rotating black holes
Physics Letters BIn a recent study, Wei et al. (2024) [96] proposed a universal classification scheme that interprets black hole solutions, including the four-dimensional Schwarzschild, Reissner-Nordström (RN), Schwarzschild-AdS, and RN-AdS black hole solutions, as ...

From rotating to charged black holes and back again
Journal of High Energy Physics, 2022 The mild form of the Weak Gravity Conjecture (WGC) requires higher derivative corrections to extremal charged black holes to increase their charge-to-mass ratio. This allows decay via emission of a smaller extremal black hole.

Thermodynamic Curvature of AdS Black Holes with Dark Energy
Frontiers in Physics, 2021 In this paper, we study the effect of dark energy on the extended thermodynamic structure and interacting microstructures of black holes in AdS, through an analysis of thermodynamic geometry.

Chaos and rotating black holes with halos [PDF]
Physical Review D, 1997 The occurrence of chaos for test particles moving around a slowly rotating black hole with a dipolar halo is studied using Poincaré sections. We find a novel effect, particles with angular momentum opposite to the black hole rotation have larger chaotic regions in phase space than particles initially moving in the same direction.

Physics Letters BWe consider the slowly rotating black hole with non-flat, non-(A)dS asymptotics and the rotating black holes with AdS asymptotics in the Einstein-Maxwell-dilaton (EMD) theory, and compare the shadows for such black holes with the Kerr-Newman-AdS black ...

Quest for realistic non-singular black-hole geometries: regular-center type
Journal of High Energy Physics, 2022 We propose seven criteria to single out physically reasonable non-singular black-hole models and adopt them to four different spherically symmetric models with a regular center and their rotating counterparts. In general relativity, all such non-singular

Classical and thermodynamic stability of black holes
, 2010 We consider the stability of black holes within both classical general relativity and the semiclassical thermodynamic description. In particular, we study linearised perturbations and their contributions to the gravitational partition function. Exploring

Topics in Core-Collapse Supernova Theory: The Formation of Black Holes and the Transport of Neutrinos [PDF]
, 2012 Core-Collapse Supernovae are one of the most complex astrophysical systems in the universe. They deeply entwine aspects of physics and astrophysics that are rarely side by side in nature.

(Quasi-)normal modes of rotating black holes and new solitons in Einstein-Gauss-Bonnet
Physics Letters BIn this paper, we analyze the scalar field (quasi-)normal modes of recently derived rotating black holes within the framework of Einstein-Gauss-Bonnet theory at the Chern-Simons point in five dimensions.
