  The recent reported gravitational wave detection motivates one to investigate
the properties of different black hole models, especially their behavior under
(axial) gravitational perturbation. Here, we study the quasinormal modes of
black holes in Weyl gravity. We derive the master equation describing the
quasinormal radiation by using a relation between the Schwarzschild-anti de
Sitter black holes and Weyl solutions, and also the conformal invariance
property of the Weyl action. It will be observed that the quasinormal mode
spectra of the Weyl solutions deviate from those of the Schwarzschild black
hole due to the presence of an additional linear $r$-term in the metric
function. We also consider the evolution of the Maxwell field on the background
spacetime and obtain the master equation of electromagnetic perturbations.
Then, we use the WKB approximation and asymptotic iteration method to calculate
the quasinormal frequencies. Finally, the time evolution of modes is studied
through the time-domain integration of the master equation.
