Fornax Euclid Quick Release 1 (Q1) Data Access and Exploration Workshop

Curious about Euclid Space Telescope data but not sure where to start? This workshop offers an introduction to the Euclid Q1 data release, including available data products and data access. You will work through Python Jupyter notebooks with hands-on exercises designed to help you understand how to use Euclid data for your science. The session will also introduce the NASA Fornax Initiative, show how it can be used to access Euclid data, and provide further hands-on experience.

Abstract: The Euclid Mission is producing an extensive archive of optical and near-infrared imaging and spectroscopy that will support research in cosmology and galaxy evolution for decades to come. The NASA/IPAC Infrared Science Archive (IRSA) hosts a Euclid archive for NASA that is complementary to the primary archive at ESA. IRSA is now serving Euclid Quick Release 1 (Q1) data, providing public access to holdings stored on-premises at IPAC and on the cloud through Amazon Web Services (AWS) under a NASA Space Act Agreement. Researchers interested in exploring Euclid data are encouraged to begin with the Euclid Data Explorer, a user-friendly interface for searching and visualizing Euclid images, catalogs, and spectra directly in the browser. Those who prefer working in the Python ecosystem can draw on a suite of tutorial notebooks that demonstrate how to access and analyze Q1 data products and make use of IRSA’s cloud deployment. To facilitate cross-catalog, cross-archive, and large-scale analyses, IRSA also provides cloud-hosted, prematched Euclid catalogs in the Parquet format, partitioned using the Hierarchical Astronomy Tiling Scheme (HATS). Looking ahead, Euclid Q1 and future cloud-hosted data sets will be accessible via Fornax—the NASA Astrophysics cloud-hosted science platform now in development—enabling users to analyze Euclid data at scale and in close proximity to other major astrophysics datasets.
