Thermodynamics of polymerized vacuum regular black holes in anti-de Sitter spacetime
Sepideh Bakhoda, Ioannis Soranidis
We derive a class of vacuum regular black holes inspired by effective loop quantum gravity dynamics and extend the construction to asymptotically anti-de Sitter spacetimes. The der…
Probing mass inflation in polymerized vacuum regular black holes via colliding null shells
Hongguang Liu, Ioannis Soranidis
We derive a class of inner-extremal regular black hole solutions characterized by a degenerate inner horizon. These geometries arise as polymerized vacuum configurations inspired b…
Regular ultracompact objects with anti-de Sitter cores as polymerized vacuum solutions
Hongguang Liu, Ioannis Soranidis
We present a systematic derivation of regular black hole solutions -- and their horizonless counterparts -- that achieve regularization via an anti-de Sitter core. These geometries…
Thermodynamics of Regular Black Holes in Anti-de Sitter Space
Robie A. Hennigar, David Kubizňák, Sebastian Murk +1
We construct regular black holes with anti-de Sitter asymptotics in theories incorporating infinite towers of higher-order curvature corrections in any dimension . We find…
Exotic Encounters: Buchdahl's Conditions and Physical Black Holes
Ioannis Soranidis, Daniel R. Terno
Black holes are among the most well-known astrophysical objects, yet their physical realisation remains conceptually subtle. We analyse physical black holes -- light-trapping regio…
Padé metrics for black hole perturbations and light rings
Swayamsiddha Maharana, Fil Simovic, Ioannis Soranidis +1
Most distinguishing features of black holes and their mimickers are concentrated near the horizon. In contrast, astrophysical observations and theoretical considerations primarily…
Properties of dynamical regular black holes in semiclassical gravity
Ioannis Soranidis
Regular black holes have become a popular alternative to the singular mathematical black holes predicted by general relativity as they circumvent mathematical pathologies associate…
Light rings and causality for nonsingular ultracompact objects sourced by nonlinear electrodynamics
Sebastian Murk, Ioannis Soranidis
We study observational signatures of nonsingular ultracompact objects regularized by nonlinear electrodynamics. The phenomenon of birefringence causes photons of different polariza…
Models of cosmological black holes
Pravin K. Dahal, Swayamsiddha Maharana, Fil Simovic +2
We study various aspects of modeling astrophysical black holes using the recently introduced semiclassical formalism of physical black holes (PBHs). This approach is based on the m…
Euclidean methods and phase transitions for the strongest deformations compatible with Schwarzschild asymptotics
Ioannis Soranidis
In this paper, we investigate the thermodynamic properties of a regular black hole model which exhibits the most significant subleading corrections to the Schwarzchild asymptotic b…
Euclidean and Hamiltonian thermodynamics for regular black holes
Fil Simovic, Ioannis Soranidis
We investigate the thermodynamic properties of the Hayward regular black hole using both Euclidean path integral and Hamiltonian methods, in asymptotically anti-de Sitter, Minkowsk…
Kinematic and energy properties of dynamical regular black holes
Sebastian Murk, Ioannis Soranidis
Nonsingular black holes have received much attention in recent years as they provide an opportunity to avoid the singularities inherent to the mathematical black holes predicted by…
Regular black holes and the first law of black hole mechanics
Sebastian Murk, Ioannis Soranidis
Singularity-free regular black holes are a popular alternative to the singular mathematical black holes predicted by general relativity. Here, we derive a generic condition that sp…
Black holes as spherically-symmetric horizon-bound objects
Pravin K. Dahal, Fil Simovic, Ioannis Soranidis +1
Working in a semi-classical setting, we consider solutions of the Einstein equations that exhibit light trapping in finite time according to distant observers. In spherical symmetr…
Matter and forces near physical black holes
Pravin Kumar Dahal, Ioannis Soranidis, Daniel R. Terno
We describe general features of formation and disappearance of regular spherically symmetric black holes in semiclassical gravity. The allowed models are critically dependent on th…
