The study of regular black holes has recently garnered significant attention, driven by the need to extend general relativity to accurately describe black hole interiors and by advances in observational technologies. Despite substantial progress in this field, significant challenges remain in identifying and characterizing physically well-motivated classes of regular black holes. In this talk,...
Regular black holes play a pivotal role in understanding effective dynamics arising from quantum gravity. In this talk, I will present a framework that maps cosmological effective dynamics onto spherically symmetric systems via Lemaitre-Tolman-Bondi (LTB) embeddings. This method allows for the reconstruction of the 1+1d effective dynamics and a 4D covariant scalar-tensor Lagrangian, derived...
Effective stellar collapse inspired by loop quantum cosmology predicts a a bounce of the stellar core when the energy density becomes planckian, and a post-bounce shell-crossing singularity/shock wave formation. I will show recent developments of the model, highlighting some of its strengths and limitations.
I will discuss aspects of the Husain-Kelly-Santacruz-Wilson-Ewing dust collapse model in effective loop quantum gravity. I will focus on rigorous causal structure analysis, in particular, I will present numerically computed Penrose-Carter diagrams for both homogeneous Oppenheimer-Snyder collapse scenario and nonhomogeneous one with a Gaussian initial dust profile. I will argue that a...
