Greybody radiation and quasinormal modes of Kerr-like black hole in Bumblebee gravity model

In the framework of the Lorentz symmetry breaking (LSB), we investigate the quasinormal modes (QNMs) and the greybody factors (GFs) of the Kerr-like black hole spacetime obtained from the bumblebee gravity model. In particular, we analyze the scalar and fermionic perturbations of the black hole within the framework of both semi-analytic WKB method and the time domain approach. The impacts of the LSB on the bosonic/fermionic QNMs and GFs of the Kerr-like black hole are investigated in detail. The obtained results are graphically depicted and discussed.

Automated summary

In the context of Lorentz symmetry breaking (LSB), the quasinormal modes (QNM) and greybody factors (GF) of the Kerr-like black hole spacetime from the bumblebee gravity model are investigated. Scalar and fermionic perturbations are analyzed using both semi-analytic WKB method and the time domain approach. The impact of LSB on the bosonic/fermionic QNM and GF of the Kerr-like black hole are examined in detail, with results depicted graphically and discussed.
