Hawking Radiation of Five-dimensional Charged Black Holes with Scalar Fields

Understand

We investigate the Hawking radiation cascade from the five-dimensional charged black hole with a scalar field coupled to higher-order Euler densities in a conformally invariant manner.

• We give the semi-analytic calculation of greybody factors for the Hawking radiation.
• Our analysis shows that the Hawking radiation cascade from this five-dimensional black hole is extremely sparse.
• The charge enhances the sparsity of the Hawking radiation, while the conformally coupled scalar field reduces this sparsity.
