Lihui Liu, Bin Wang, Guohong Yang
TL;DR
This paper investigates how extra dimensions influence the energy absorption spectra of brane-world black holes by analyzing scalar and gravitational wave dynamics, revealing signatures of higher dimensions.
Contribution
It introduces a study of wave absorption in brane-world black holes, highlighting the impact of extra dimensions on energy spectra, which is a novel comparison with four-dimensional black holes.
Findings
Extra dimension signatures appear in energy absorption spectra.
Wave dynamics differ from four-dimensional Schwarzschild black holes.
Results suggest potential observational signatures of extra dimensions.
Abstract
We have studied the wave dynamics and the energy absorption problem for the scalar field as well as the brane-localized gravitational field in the background of a braneworld black hole. Comparing our results with the four-dimensional Schwarzschild black hole, we have observed the signature of the extra dimension in the energy absorption spectrum.
