Introduction | Getting started | Resources

Introduction

The Cherenkov Telescope Array Observatory (CTAO) is the next generation ground-based observatory for gamma-ray astronomy at very-high energies. Gammapy was chosen on June 1^st 2021 to be the official Science Analysis Tool library for the CTAO (see CTAO news).

This page provides some information and links to useful resources concerning simulation and analysis of CTAO data with Gammapy. Most of the pages we link here require a CTAO user account to access the information.

Getting started

To learn how to use Gammapy for CTAO analysis, use the Gammapy tutorials. We suggest you first consult the "Getting started" page. Then continue with the "CTAO with Gammapy" tutorial, followed by the "3D map simulation" tutorial.

If you have any questions, please post on the Gammapy CTAO mailing list or contact the Gammapy coordination committee (see Gammapy contact page)

Please note that Gammapy is a very young project and is under heavy development. At the moment we are participating in the CTAO first data challenge, fixing issues and adding new functionality for CTAO.

Resources

• CTA first data challenge (CTA DC-1) page - this page contains information about data, sky models, links to forums for discussion and checks, ... (private access with the old access system)
• cta-analyses - a private repository on Github that we use to share analysis scripts and notebooks that use CTAO-internal data and IRFs. The main purpose is to make it easy to collaborate on issues and code. Eventually results should be shared on the official CTAO pages of course! To get access, send an email to Bruno Khélifi or anyone else that you know that is involved in Gammapy and CTAO.
• If you're doing simulations or analysis for CTAO with Gammapy and would like to discuss your results or get help, please join the Gammapy mailing list, and the regular Gammapy calls.
