We investigate the massless scalar field perturbations, focusing on the quasinormal modes spectrum and the ringdown waveform of regular black hole spacetimes derived within the Asymptotic Safety program. In particular, we discuss the stability of a new class of AS black holes recently derived dynamically within a non-singular model of collapse and explore the possibility of detecting signatures of the horizon structure with high-order overtones.

  1. Quasinormal modes of Bonanno-Reuter black holes via the Spectral Method

    gr-qc 2026-07 accept novelty 6.0 of 10

    Spectral Method yields the complete QNM spectrum (fundamentals, overtones, overdamped modes) of the Bonanno-Reuter black hole, missed by prior WKB analyses.

  2. Cosmological scalar perturbations in Horndeski-like gravity

    gr-qc 2025-01 conditional novelty 4.0 of 10

    For a Horndeski-like scalar-tensor model with a chosen background solution, scalar stability and entropy-production bounds restrict the coupling gamma to be non-positive and constrain gamma*Lambda relative to alpha.
