We study quasinormal modes related to gravitational and electromagnetic perturbations of spherically symmetric charged black holes in nonlinear electrodynamics. Beyond the linear Maxwell electrodynamics, we consider a class of Lagrangian with higher-order corrections written by the electromagnetic field strength and its Hodge dual with arbitrary coefficients, and we parametrize the corrections for quasinormal frequencies in terms of the coefficients. It is confirmed that the isospectrality of quasinormal modes under parity is generally violated due to nonlinear electrodynamics. As applications, the corrections for quasinormal frequencies in Euler-Heisenberg and Born-Infeld electrodynamics are calculated, then it is clarified that the nonlinear effects act to lengthen the oscillation period and enhance the damping rate of the quasinormal modes.

Probing nonlinear electrodynamics-sourced black holes via light and orbital mechanics
For ModMax black holes, Shapiro time delay and gravitational redshift are identical for both photon polarizations, while Sagnac and kinematic shifts distinguish them; S2 precession bounds e^-gamma (Q/2M)^2 <= 0.135.

A causal magnetic black hole with finite self-energy
A positive power-kernel mixture in nonlinear electrodynamics yields an exact magnetic black hole whose metric is strictly increasing for nonnegative mass parameter, giving at most one horizon and no inner Cauchy horiz...

Causality Constraints on Black Hole Thermodynamics in Nonlinear Electrodynamics
Causality in nonlinear electrodynamics forces the entropy-to-mass-squared ratio of black holes to decrease with mass and the extremal mass-to-charge ratio to increase with charge.

Influence of Perfect Fluid Dark Matter on Shadow Observables of Yang-Mills modified charged black holes
A rotating Yang-Mills charged black hole surrounded by perfect fluid dark matter is shown to have a smaller and more distorted shadow as the dark matter parameter increases, with EHT-derived bounds on the dark matter ...

Quasinormal Modes of Schwarzschild Black Holes in the Dehnen-(1, 4, 5/2) Type Dark Matter Halos
Quasinormal mode frequencies of a Schwarzschild black hole in a Dehnen-(1,4,5/2) dark matter halo are computed and found to decrease as halo density or core radius increases, with stability preserved.
