Inner Horizon Instability in Reissner-Nordström Black Holes Due to Quantum Field Theory Effects
The quantum vacuum near a black hole's inner horizon (Cauchy horizon) significantly impacts its stability, potentially leading to singularity formation, as explored through the lens of the anomaly-induced effective action (AIEA) method.

Field Redefinition Invariance of Higher-Derivative Corrections to Kerr-Newman Black Hole Multipole Moments
This research paper demonstrates that higher-derivative corrections to the multipole moments of a Kerr-Newman black hole are invariant under field redefinitions, confirming their validity as physical observables in effective quantum gravity theories.
The Potential Role of the Black Hole Singularity in Black Hole Entropy and Information Loss
The entropy of a black hole might be located within the singularity itself, challenging the prevailing view that it resides at the event horizon. This perspective suggests a natural mechanism for information loss during black hole evaporation, as the singularity operates outside the realm of standard quantum theory.
The Impossibility of Detecting Deviations from Einstein's Gravity in Black Hole Ringdowns within Weakly Coupled Gravity Theories
Higher-derivative gravity theories, often proposed as extensions to Einstein's theory of gravity, are unlikely to produce detectable deviations in the quasinormal mode (QNM) spectrum of black hole ringdowns due to causality constraints.
Microscopic Analysis of a Non-Supersymmetric Extremal Black Hole Reveals a Unique Ground State
Contrary to the common belief that extremal black holes possess significant ground state degeneracy, this research, using a microscopic D-brane model, demonstrates that a non-supersymmetric extremal black hole has a unique ground state with non-zero energy.
The Impact of the No-Hair Theorems on the Jet Precession of M87*
The no-hair theorems, which dictate the relationship between a black hole's mass and spin, successfully explain the observed precession of the M87* jet, suggesting the importance of both the Lense-Thirring effect and the black hole's quadrupole moment in this phenomenon.
Next-to-Leading Order Corrections Improve Analytical Calculation of Scalar Perturbations in Kerr-Anti-de Sitter Black Holes
Incorporating next-to-leading order corrections significantly improves the accuracy of analytical calculations for scalar perturbations in Kerr-anti-de Sitter black holes, particularly for the real part of eigenfrequencies, which was insensitive to black hole spin at leading order.
