Novel black-bounce spacetimes: wormholes, regularity, energy conditions, and causal structure
We develop a number of novel “black-bounce” spacetimes. These are specific regular black
holes where the area radius always remains nonzero, thereby leading to a “throat” that is …

[HTML][HTML] Thermal stability with emission energy and Joule–Thomson expansion of regular BTZ-like black hole
We investigate the thermodynamic properties and Joule–Thomson expansion for conical or
BTZ-like black holes. To analyze the thermal stability, we discuss the temperature and …

Slowly rotating black holes in nonlinear electrodynamics
D Kubizňák, T Tahamtan, O Svitek - Physical Review D, 2022 - APS
We show how (at least, in principle) one can construct electrically and magnetically charged
slowly rotating black hole solutions coupled to nonlinear electrodynamics (NLE). Our …

Kasner eons with matter: holographic excursions to the black hole singularity
A bstract Recent work has shown that introducing higher-curvature terms to the Einstein-
Hilbert action causes the approach to a space-like singularity to unfold as a sequence of …
