Overtones' outburst and Hawking evaporation of Kazakov-Solodukhin quantum corrected black hole
read the original abstract
The Kazakov-Solodukhin black hole metric represents a spherically symmetric deformation of the Schwarzschild solution due to quantum-gravity corrections. Assuming the absence of nonspherical deformations of the metric, this problem was solved nonperturbatively. In this study, we investigate the intensity of Hawking radiation in the background of such quantum-corrected black holes and the behavior of their quasinormal modes (QNM). Our findings indicate that while the geometry and such classical characteristics as the fundamental QNM frequencies or the shadow radius are only slightly altered, the Hawking radiation and the frequencies of QNM overtones of sufficiently small black holes change much more significantly. This Hawking radiation enhancement arises due to much larger grey-body factors, while the Hawking temperature remains unaffected. The effect becomes significant at the latest stage of black hole evaporation.

Ces\`aro convergence of the high-order WKB method and its applications to black-hole overtones and long-lived modes
High-order WKB with Padé approximants and Cesàro means enables computation of black-hole overtones and long-lived quasinormal modes, with a noted limitation that apparent convergence can be incorrect for some metrics.
