Quasinormal modes and shadow of Schwarzschild-Tangherlini black hole with GUP
J. A. V. Campos, M. A. Anacleto, F. A. Brito +2
In this work, we investigate quasinormal modes and the shadow of a Schwarzschild-Tangherlini black hole in dimensions, incorporating corrections arising from the Generalize…

Absorption and quasinormal modes by rotating acoustic black holes in Lorentz-violating background
J. A. V. Campos, M. A. Anacleto, F. A. Brito +2
In this work, we investigate the effects of Lorentz symmetry violation on the absorption cross section and quasinormal modes of a rotating acoustic black hole in (2+1) dimensions,…
