Results: Data releases Research Unit 2
One of the WP designed for the project included all activities related to data reduction and analysis. Under this WP we carried out the data reduction analysis and release of both spectroscopic and photometric data sets. Here are the most important releases
GLASS-JWST ERS +DDT2756 spectroscopic release
We release fully reduced spectra obtained with NIRSpec onboard JWST as part of the GLASS-JWST Early Release Science Program and a follow-up DDT program 2756. We derived redshifts, described sample selection and characterised its completeness as a function of redshift and apparent magnitude GLASS spectroscopy (Mascia et al. 2024, Astronomy & Astrophysics, Volume 690, A2.). The release is available through MAST.
MULTIFIELD PHOTOMETRIC CATALOGS
We then presented a set of photometric catalogues aimed at providing the community with a comprehensive database for the study of galaxy populations in the high-redshift Universe. The set gathers data from eight JWST NIRCam observational programs, targeting the Abell 2744, EGS, COSMOS, UDS, GOODS North and South deep fields for total area of ≃0.2 sq. degrees. We obtained photometric estimates including tailored improvements designed to enhance the performance on the specific dataset. A grand total of ~530 thousand sources were detected and presented. We also provide photometric redshift estimates, statistically validated against a large set of robust spectroscopic data. The catalogues are publicly available on the ASTRODEEP website. http://www.astrodeep.eu/ and presented in a paper (Merlin et al. 2024 Astronomy & Astrophysics, Volume 691, id.A240).
JWST GO-3073 spectroscopic release
JWST NIRSpec PRISM spectra obtained with proprietary program GO-3073 which observed the GLASS JWST field have been publicly released. The reduced 1D and 2D spectra and the redshift measurements for 600 high redshift galaxies are publicly available at the ASTRODEEP website http://www.astrodeep.eu and presented in a paper (Castellano et al. 2025 submitted to Astronomy and Astrophysics 10.48550/arXiv.2512.08490)
