Black Holes in Asymptotic Safety: A Review of Solutions and Phenomenology
Andrea Spina
Asymptotic Safety offers a conservative and predictive framework for quantum gravity, based on the existence of a renormalization group fixed point that ensures ultraviolet complet…
Veiled Singularities in Einstein-Weyl Gravity: Stability and Physical Interpretation of Horizonless Solutions
Alfio M. Bonanno, Samuele Silveravalle, Andrea Spina
We investigate a class of horizonless solutions in Einstein-Weyl gravity, corresponding to the so-called attractive naked singularities of the (-2,2) type. In contrast to General R…
Regular Black Holes from Proper-Time flow in Quantum Gravity and their Quasinormal modes, Shadow and Hawking radiation
Alfio Bonanno, Roman A. Konoplya, Giovanni Oglialoro +1
We derive a class of regular black holes from the proper-time renormalization group approach to asymptotically safe gravity. A central challenge is the robustness of physical predi…
Time Evolution of Black Hole Perturbations in Quadratic Gravity
Roman A. Konoplya, Andrea Spina, Alexander Zhidenko
We study the full time-domain evolution of gravitational perturbations in black hole spacetimes arising in Einstein-Weyl gravity, a renormalizable extension of general relativity c…
