Stability Analysis of Scalar Perturbations Around a Magnetized Compact Object in General Relativity
The exterior region of a magnetized compact object, modeled using a modified Gutsunaev-Manko spacetime, is found to be stable under scalar perturbations, with the magnetization of the central object enhancing the stability by increasing the decay rate of perturbations.
Quasinormal Modes of a Massless Scalar Field in the Near-Nariai Limit of the Plebański-Demiański Black Hole
This paper analytically derives the quasinormal frequencies for a massless scalar field conformally coupled to gravity in the near-Nariai limit of the Plebański-Demiański black hole, demonstrating that the decay rate is quantized and depends only on the black hole's surface gravity.
Exploring the Impact of Semi-Classical Physics on the Quasinormal Mode Spectra of Black Holes
This paper investigates how semi-classical effects near the event horizon of a black hole, characterized by deviations from the Schwarzschild metric, influence the frequencies and damping times of its quasinormal modes, offering a potential method for detecting these subtle deviations through gravitational wave observations.
New Pairs of Purely Damped Quasinormal Modes Discovered in a Hot and Dense Strongly-Coupled Plasma
This research paper presents the discovery of a new structure of purely damped quasinormal modes (QNMs) in a hot and dense strongly-coupled plasma, modeled using the 2 R-Charge Black Hole (2RCBH) holographic construction. These new QNMs, characterized by purely imaginary frequencies, dominate the late-time equilibration of the plasma at high chemical potentials, suggesting upper bounds on equilibration times that cannot be surpassed by further doping.

Quasinormal Modes of Slowly-Spinning Horizonless Compact Objects: An Analysis Using the Membrane Paradigm
Spinning horizonless compact objects, as opposed to black holes, can be differentiated by their unique quasinormal mode (QNM) spectrum, which is influenced by their compactness and reflectivity, properties best analyzed through the membrane paradigm framework.
