Quasinormal Modes and Hawking Radiation of Black Holes with Primary Scalar Hair
Roman Konoplya, Oleksandr Stashko, ZdenÄk StuchlÃk
Recently, a new family of asymptotically flat black-hole solutions endowed with primary scalar hair has been discovered in beyond-Horndeski gravity. We study in detail the quasinor…

Transition from Regular Black Holes to Wormholes in Covariant Effective Quantum Gravity: Scattering, Quasinormal Modes, and Hawking Radiation
R. A. Konoplya, O. S. Stashko
Utilizing the Hamiltonian constraints approach, a quantum-corrected solution has been derived \cite{Zhang:2024ney}, which describes either a regular black hole or a traversable wor…

Probing the Effective Quantum Gravity via Quasinormal Modes and Shadows of Black Holes
R. A. Konoplya, O. S. Stashko
Two quantum-corrected black hole models have recently been proposed within the Hamiltonian constraints approach to quantum gravity, maintaining general covariance \cite{Zhang:2024k…
