Quasinormal modes and Hawking radiation of a Reissner-Nordstr\"om black hole surrounded by quintessence

TL;DR

This paper studies how quintessence influences the quasinormal modes and Hawking radiation of a Reissner-Nordström black hole, revealing slower damping and radiation rates due to quintessence interaction.

Contribution

It provides a detailed analysis of the effects of quintessence on black hole quasinormal modes and Hawking radiation using the WKB method, highlighting the impact of quintessence density.

Findings

Quasinormal modes damp more slowly with increased quintessence density.

Black hole radiation rate decreases as quintessence density increases.

Quintessence interaction alters the black hole's dynamical and radiative properties.

Abstract

We investigate quasinormal modes (QNMs) and Hawking radiation of a Reissner-Nordstr\"om black hole sur-rounded by quintessence. The Wentzel-Kramers-Brillouin (WKB) method is used to evaluate the QNMs and the rate of radiation. The results show that due to the interaction of the quintessence with the background metric, the QNMs of the black hole damp more slowly when increasing the density of quintessence and the black hole radiates at slower rate.
