Available Data

HETDEX will ultimately include source spectra for over 1 million Lyman Alpha Emitters at 1.9<z<3.5, 1 million OII emitting galaxies at z<0.5, 30K 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.

Data Access

Currently, the first Active Galactic Nuclei catalog may be accessed via the Texas Advanced Computing Center.

Access Data

HETDEX Jupyter Lab

The public may gain access and query tools to public HETDEX data using the Texas Advanced Computing Center (TACC) Jupyter Lab service. A TACC account is required to sign up.
