High-energy properties of the graviton scattering in quadratic gravity

Yugo Abe, Takeo Inami, Keisuke Izumi

We obtain the matter-graviton scattering amplitude in the gravitational theory of quadratic curvature, which has term in the action. Unitarity bound is not satisfied bec…

Spectroscopy of Kerr-AdS spacetime with the Heun function: Quasinormal modes, greybody factor, and evaporation

Sousuke Noda, Hayato Motohashi

We investigate quasinormal modes, greybody factor, and Hawking evaporation of a five-dimensional Kerr-anti de Sitter (AdS) black hole by solving a wave equation for a test mass…

Evaporation of Echoing Black Holes

Naritaka Oshita, Hayato Motohashi, Sousuke Noda

We compute the graybody factor and evaporation rate of a rotating black hole in the presence of a hypothetical reflective surface slightly outside the outer horizon radius, assumin…
