Abstract

We present GammaPBHPlotter, a public Python code for calculating and plotting the Hawking radiation gamma-ray spectra of primordial black holes in the mass range of $10^{14}$ to $10^{18}$ grams. This tool allows users to compute the monochromatic and mass-averaged spectra of black holes over a range of parameters. We include the primary/direct Hawking emission, the secondary emission from the decay and hadronization of unstable particles, the final state radiation, and the in-flight annihilation gamma-ray emission components.
