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…

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…

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…

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…
