Recently, it was shown that power-Maxwell (PM) theory can remove the singularity of electric field [1]. Motivated by great interest in three-dimensional black holes and a surge of success in studying massive gravity from both the cosmological and astrophysical point of view, we investigate such black hole solutions in de Rham, Gabadadze and Tolley (dRGT) massive theory of gravity in the presence of PM electrodynamics. First, we extract exact three-dimensional solutions in the PM-dRGT massive gravity. Then we study geometrical properties including type of singularity and asymptotic behavior, and show that although there is a singularity at the origin for asymptotical (A)dS, only AdS solutions are covered by an event horizon. Calculating conserved and thermodynamic quantities, we check the validity of the first law of thermodynamics for the corresponding solutions and examine the stability of these black holes in context of canonical ensemble. We continue with the calculation of the optical features of this kind of black holes such as the shadow geometrical shape, the energy emission rate and the deflection angle. Taking into account these optical quantities, we analysis the effective role of the parameters of models on them. We also employ the correspondence between the quasinormal modes in the eikonal limit and shadow radius to study the scalar field perturbations in these backgrounds. Finally, we take advantage of the WKB method and investigate how the quasinormal modes will be disturbed for massive particles.

We compute the quasinormal frequencies for scalar perturbations of hairy black holes in fourdimensional Einstein-Maxwell-dilaton theory assuming a non-trivial scalar potential for the dilaton field. We investigate the impact on the spectrum of the angular degree, the overtone number, the charges of the black hole as well as the magnitude of the scalar potential. All modes are found to be stable. Our numerical results are summarized in tables, and for better visualization, we show them graphically as well.

“…To that end, let us consider the propagation of a test scalar field, Φ, which is assumed to be real, massive, electrically neutral, and canonically coupled to gravity, in a fixed gravitational background. Its wave equation is given by the usual Klein-Gordon equation, see e.g., [65][66][67][68] 1…”

We compute the quasinormal frequencies for scalar perturbations of charged black holes in five-dimensional Einstein-power-Maxwell theory. The impact on the spectrum of the electric charge of the black holes, of the angular degree, of the overtone number, and of the mass of the test scalar field is investigated in detail. The quasinormal spectra in the eikonal limit are computed as well for several different spacetime dimensionalities. arXiv:2005.08338v2 [gr-qc] 7 Jun 2020
