Quasinormal modes of scalar and Dirac perturbations of Bardeen de-Sitter black holes
Wadbor Wahlang, Piyush A. Jeena, S. Chakrabarti
So far the study of black hole perturbations has been mostly focussed upon the classical black holes with singularities at the origin and hidden by event horizon. Compared to that,…
