Scalar perturbations and quasi-normal modes of a non-linear magnetic-charged black hole surrounded by quintessence

Understand

We study scalar perturbations and quasinormal modes of a nonlinear magnetic charged black hole surrounded by quintessence.

• Time evolution of scalar perturbations is studied for different parameters associated with the black hole solution.
• We also study the reflection and transmission coefficients along with absorption cross-section for the considered black hole spacetime.
• It was shown that the real part of quasinormal frequency increases with increase in nonlinear magnetic charge while the module of the imaginary part of the frequency decreases.
