DATA RELEASE

July 18, 2025: Data from the z-GAL Large Program conducted with NOEMA are now being released. This new release significantly expands the accessible dataset from the Pilot Program and provides the community with a wealth of information on high-redshift galaxies observed with NOEMA.

Researchers interested in exploring or making use of these data are asked to cite one or more of the relevant references listed below, to acknowledge the efforts of the z-GAL team and the NOEMA observatory. These references provide essential context and scientific background for the observations and data products.

• z-GAL: A NOEMA spectroscopic redshift survey of bright Herschel galaxies. I. Overview (Cox et al. 2023, A&A, 678, A26)
• z-GAL: A NOEMA spectroscopic redshift survey of bright Herschel galaxies. II. Dust properties (Ismail et al. 2023, A&A, 678, A27)
• z-GAL: A NOEMA spectroscopic redshift survey of bright Herschel galaxies. III. Physical properties (Berta et al. 2023, A&A, 678, A28)
• NOEMA redshift measurements of bright Herschel galaxies (Neri et al. 2020, A&A, 635, A7)

December 01, 2020: The z-GAL Team makes the data release (DRP) of the Pilot Project public. The links below provide access to the core data products obtained with NOEMA as part of the precursor project to the z-GAL Large Program. A README file is provided that contains a description of the data released.

• The DRP is available for download in the FITS (302 MB, not available yet) and GILDAS (304 MB) formats. If you make use of the data in your research, please refer to the publication by Neri et al. 2020, A&A, 635, A7 from which the data originated.

December 01, 2020: First data release (DR1) of the z-GAL Large Program. Access to the data will only be possible when the framework conditions allowing the data release will be in place.
