چکیده
In this paper, we study the shadow of a 4D Einstein–Gauss–Bonnet black hole as photons couple to Weyl tensor and find that propagation light depends on its polarization which leads existence double shadow. Then, discuss effect coupling parameter [Formula: see text], Gauss–Bonnet constant text] Further, explore influence quasinormal modes (QNMs) massless scalar field investigate connection between real part QNMs in eikonal limit radius holes. We limit, is inversely proportional under case uncoupled tensor.

Connection between black-hole quasinormal modes and lensing in the strong deflection limit.
The purpose of the current Letter is to give some relations between gravitational lensing in the strong-deflection limit and the frequencies of the quasinormal modes of spherically symmetric, asymptotically flat black holes. On the one side, the relations obtained can give a physical interpretation of the strong-deflection limit parameters. On the other side, they also give an alternative metho...
متن کاملBlack Hole Determinants and Quasinormal Modes
We derive an expression for functional determinants in thermal spacetimes as a product over the corresponding quasinormal modes. As simple applications we give efficient computations of scalar determinants in thermal AdS, BTZ black hole and de Sitter spacetimes. We emphasize the conceptual utility of our formula for discussing ‘1/N ’ corrections to strongly coupled field theories via the hologr...
متن کاملQuasinormal modes of a black hole surrounded by quintessence
Using the third-order WKB approximation, we evaluate the quasinormal frequencies of massless scalar field perturbation around the black hole which is surrounded by the static and spherically symmetric quintessence. Our result shows that due to the presence of quintessence, the scalar field damps more rapidly. Moreover, we also note that the quintessential state parameter ǫ (the ratio of pressur...
متن کاملNeutrino quasinormal modes of the Reissner-Nordström black hole
Abstract: The neutrino quasinormal modes of the Reissner-Nordström (RN) black hole are investigated using continued fraction approach. We find, for large angular quantum number, that the quasinormal frequencies become evenly spaced and the spacing of the real part depends on the charge of the black hole and that of the imaginary part is zero. We then find that the quasinormal frequencies in the...
متن کاملConsiderations on the excitation of black hole quasinormal modes
We provide some considerations on the excitation of black hole quasinormal modes (QNMs) in different physical scenarios. Considering a simple model in which a stream of particles accretes onto a black hole, we show that resonant QNM excitation by hyperaccretion requires a significant amount of fine-tuning, and is quite unlikely to occur in nature. Then we summarize and discuss present estimates...
