gamma-sky.net: Portal to the Gamma-Ray Sky

TL;DR

gamma-sky.net is an interactive, open-source web portal that visualizes gamma-ray sky data from Fermi-LAT and other surveys, enabling both professional and public exploration of gamma-ray sources and their multi-wavelength counterparts.

Contribution

The paper introduces gamma-sky.net, a novel interactive platform integrating gamma-ray data with multi-wavelength surveys for comprehensive sky exploration.

Findings

Provides interactive pan and zoom navigation.

Overlays major gamma-ray source catalogs.

Includes detailed source information and literature references.

Abstract

Gamma-sky.net is a novel interactive website designed for exploring the gamma-ray sky. The Map View portion of the site is powered by the Aladin Lite sky atlas, providing a scalable survey image tesselated onto a three-dimensional sphere. The map allows for interactive pan and zoom navigation as well as search queries by sky position or object name. The default image overlay shows the gamma-ray sky observed by the Fermi-LAT gamma-ray space telescope. Other survey images (e.g. Planck microwave images in low/high frequency bands, ROSAT X-ray image) are available for comparison with the gamma-ray data. Sources from major gamma-ray source catalogs of interest (Fermi-LAT 2FHL, 3FGL and a TeV source catalog) are overlaid over the sky map as markers. Clicking on a given source shows basic information in a popup, and detailed pages for every source are available via the Catalog View component of the website, including information such as source classification, spectrum and light-curve plots, and literature references. We intend for gamma-sky.net to be applicable for both professional astronomers as well as the general public. The website started in early June 2016 and is being developed as an open-source, open data project on GitHub (https://github.com/gammapy/gamma-sky). We plan to extend it to display more gamma-ray and multi-wavelength data. Feedback and contributions are very welcome!
