Abstract

We introduce and describe GrayHawk, a publicly available Mathematica-based tool designed for the efficient computation of gray-body factors for spherically symmetric and asymptotically flat black holes. This program provides users with a rapid and reliable means to compute gray-body factors for massless fields with spin

s = 0, 1 / 2, 1, 2

in modes specified by the angular quantum number

l

, given a black hole metric and the associated parameter values.

GrayHawk is preloaded with seven different black hole metrics, offering immediate applicability to a variety of theoretical models. Additionally, its modular structure allows users to extend its functionality easily by incorporating alternative metrics or configurations. This versatility makes GrayHawk a powerful and adaptable resource for researchers studying black hole physics and Hawking radiation.

The codes described in this work are publicly available at https://github.com/marcocalza89/GrayHawk
