Quasinormal modes and GUP-corrected Hawking radiation of BTZ black holes within modified gravity frameworks by Faizuddin Ahmed, Ahmad Al-Badawi, İzzet Sakallı, Abdelmalek Bouzenada

“…The findings indicate that increasing mass and parameter values results in a raised potential barrier, implying stronger confinement of perturbations and impacting black hole stability. Incorporating the generalized uncertainty principle, we also study its effect on the thermodynamics of rotating BTZ black holes, demonstrating how GUP modifies black hole radiation, potentially observable in QNM decay rates. …”

A Dual Active Black Hole Candidate with Mass Ratio ~7:1 in a Disk Galaxy by Xiao Cao, Yan-Mei Chen, Yong Shi, Junfeng Wang, Zhijie Zhou, Min Bao, Qiusheng Gu, Alexei Moiseev, Luis C. Ho, Lan Wang, Guangquan Zeng

“…Considering almost every massive galaxy is associated with multiple dwarf satellites around it, minor mergers involving galaxies with disproportional stellar masses should be much more common than major mergers, which would naturally lead to black hole (BH) pairs with significantly different masses. …”

Gravitational odd-parity perturbation of a Horndeski hairy black hole: quasinormal mode and parameter constraint by Zhen-Hao Yang, Yun-He Lei, Xiao-Mei Kuang, Bin Wang

“…Abstract During the binary black hole coalescence, gravitational waves emitted at the ringdown stage can be well described by black hole perturbation theory, where the quasinormal modes (QNMs) become the important ingredient in modeling the pattern waveform. …”

Hawking Radiation-Quasi-Normal Modes Correspondence and Effective States for Nonextremal Reissner-Nordström Black Holes by C. Corda, S. H. Hendi, R. Katebi, N. O. Schmidt

“…It is known that the nonstrictly thermal character of the Hawking radiation spectrum harmonizes Hawking radiation with black hole (BH) quasi-normal modes (QNM). This paramount issue has been recently analyzed in the framework of both Schwarzschild BHs (SBH) and Kerr BHs (KBH). …”

Heun-Type Solutions of the Klein-Gordon and Dirac Equations in the Garfinkle-Horowitz-Strominger Dilaton Black Hole Background by Marina-Aura Dariescu, Ciprian Dariescu, Cristian Stelea

“…We study the Klein-Gordon and the Dirac equations in the background of the Garfinkle-Horowitz-Strominger black hole in the Einstein frame. Using a SO(3,1)×U(1)-gauge covariant approach, as an alternative to the Newman-Penrose formalism for the Dirac equation, it turns out that these solutions can be expressed in terms of Heun confluent functions and we discuss some of their properties.…”
