The signals from the brane-world black Hole

TL;DR

This paper investigates wave behavior and Hawking radiation of scalar and gravitational fields around a braneworld black hole with tidal charge, revealing signatures of extra dimensions in these phenomena.

Contribution

It introduces analysis of wave dynamics and Hawking radiation in a braneworld black hole with tidal charge, highlighting effects of extra dimensions.

Findings

Tidal charge influences wave propagation and Hawking radiation signals.

Extra dimension signatures are observable in both wave dynamics and radiation.

Differences from four-dimensional black holes are characterized by tidal charge effects.

Abstract

We have studied the wave dynamics and the Hawking radiation for the scalar field as well as the brane-localized gravitational field in the background of the braneworld black hole with tidal charge containing information of the extra dimension. Comparing with the four-dimensional black holes, we have observed the signature of the tidal charge which presents the signals of the extra dimension both in the wave dynamics and the Hawking radiation.
