Quasinormal modes of a black hole in the deformed Horava-Lifshitz gravity
Abstract
We study the quasinormal modes of the massless scalar perturbation in the background of a deformed black hole in the Horava-Lifshitz gravity with coupling constant λ=1. Our results show that the quasinormal frequencies depend on the parameter in the Horava-Lifshitz gravity and the behavior of the quasinormal modes is different from those in the Reissner-Norstr\"om and Einstein-Born-Infeld black hole spacetimes. The absolute value of imaginary parts is smaller and the scalar perturbations decay more slowly in the deformed Horava-Lifshitz black hole spacetime. This information can help us understand more about the Horava-Lifshitz gravity.
