Available Data

HETDEX will ultimately include source spectra for over 1 million Lyman Alpha Emitters at 1.9<z<3.5, 0ver 0.5 million OII emitting galaxies at z<0.5, 20K Active Galactic Nuclei, 200 K stars, and an additional 50K low-redshift galaxies.

Our aim is to release all our sources and provide access to the over 600 million fiber spectra collected for HETDEX. Currently, HETDEX AGN Catalogs 1 and 2 and HETDEX Source Catalog 1 are available for download.

HETDEX Jupyter Lab

When the HETDEX Public Data is released, the public may gain access to HETDEX Public data products and public catalogs using the Texas Advanced Computing Center (TACC) Jupyter Lab service. A TACC account is required to sign up.  This will give you open access to the HETDEX Public JupyterHub. Note that no other TACC resources may be accessed without a project allocation and you must download interested data products and save your work on your local machine.

Steps to Access the HETDEX JupyterHub:

1. Get a TACC account here.
2. Sign up for access to the hub in this form.
3. Sign into the HETDEX JupyterHub.

Can’t Access the Hub?

Notebooks at https://github.com/HETDEX/dexcube demonstrate how to query the data release and download compressed datacubes of interest. The datacubes are password protected and only available for internal use.
