$\gamma$-Cascade: A Simple Program to Compute Cosmological Gamma-Ray Propagation

Understand

Modeling electromagnetic cascades during gamma-ray transport is important in many applications within astrophysics.

• This document introduces $\gamma$-Cascade, a publicly available Mathematica package which allows users to calculate observed gamma-ray fluxes from point sources as well as from a distribution of sources.
• $\gamma$-Cascade semi-analytically computes the effects of electromagnetic interactions during gamma-ray transport.
