Greybody factor for an electrically charged regular-de Sitter black holes in $d$-dimensions

Abstract

In this article, we study the propagation of scalar fields in the gravitational background of a spherically symmetric, electrically charged, regular-de Sitter black holes in higher dimensions. We carry out a thorough investigation of the grey body factors, by deriving analytical expressions for both minimally and non-minimally coupled scalar fields. Then we study the profile of grey body factors in terms of particle properties, namely the angular momentum quantum number and the non-minimal coupling constant, and the spacetime properties, namely the dimension, the cosmological constant and the non-linear charge parameter. We then derive the Hawking radiation spectra for a higher-dimensional electrically charged regular-de Sitter black hole. We find that the non-minimal coupling may suppress the greybody factor and the non-linear charge parameter may enhance it, but they both suppress the energy emission rate of Hawking radiation.

“…We have extended this work for modified charged AdS BH and discussed the effects of physical parameters on GBF. The GBF for a regular de Sitter BH coupled (minimally/non-minimally) with non-linear charge is analyzed in [34]. We have found that the effective potential of the BH increases with an increase in both the mass and electric charge parameters (q m and q e ).…”

“…The absorption rate of BH for non-minimally coupled massless scalar field with strings was studied in [33]. Ali et al [34] studied the GBF of a spherically symmetric charged regular de Sitter BH in higher dimensions. They found that the non-minimal coupling reduces the GBF while the non-linear charge increases the GBF.…”
