Fermionic and bosonic greybody factors as well as quasinormal modes for charged Taub NUT black holes

The paper studies the spinorial wave equations, namely Dirac and Klein–Gordon as well greybody radiations quasinormal modes (QNMs) of charged Taub NUT black hole (CTNBH). To obtain fermionic factors (GFs) QNMs, we study fermions by employing equation. this end, use a null tetrad in Newman–Penrose formalism. Then, separate equation into radial angular sets. Using obtained convert them typical one dimensional Schrödinger-like equations with aid tortoise coordinate derive effective potentials. For bosonic GFs CTNBH geometry We then potential investigate effect parameter on it. show that while QNMs individually increase increasing parameter, is overwhelmingly greater than QNMs.
