Quasinormal modes of a black hole in the deformed Horava-Lifshitz gravity

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 lambda = 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-Norstrom and Einstein-Born-lnfeld 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. (C) 2010 Elsevier B.V. All rights reserved.
