What is Gammapy?

Gammapy is an open-source Python package for gamma-ray analysis built on Numpy and Astropy.

It is used as core library for the Science Analysis tools of Cherenkov Telescope Array (CTA), and can be used to analyse data from existing gamma-ray telescopes.

Gammapy is a community-developed, open-source Python package for gamma-ray astronomy. It is an in-development affiliated package of Astropy that builds on the core scientific Python stack to provide tools to simulate and analyse the gamma-ray sky for telescopes such as CTA, H.E.S.S., VERITAS, MAGIC, HAWC and Fermi-LAT. Gammapy is a place for Python-coding gamma-ray astronomers to share their code and collaborate. Feature requests and contributions welcome! Likelihood fitting of the morphology and spectrum of gamma-ray sources (using Sherpa), including multi-mission joint likelihood analysis and physical SED modeling (using Naima) is one important feature we’re working on. But Gammapy has a broader scope, we currently have code e.g. for data handling, background modeling, source detection, easy access to c ommonly used datasets and catalogs, statistical methods, even simulating Galactic source populations.
