A Value-Added Physical Properties Catalog for Low-redshift Galaxies from DESI Legacy Imaging Surveys DR10
Shirui Wei
This catalog provides estimates of galaxy physical properties for the DESI Legacy Imaging Surveys Data Release 10 (LS DR10). It includes star formation rate, stellar mass, and gas-phase oxygen abundance for approximately 547 million galaxies at low redshift. The physical properties are derived using a multimodal deep learning approach that jointly incorporates imaging data and photometric catalog features. In addition to the predicted physical properties, the dataset also provides a set of photometric features used during model training and estimation for reference. This catalog represents the first physical properties catalog for DESI LS DR10 that simultaneously provides star formation rate, stellar mass, and metallicity estimates derived with a deep learning approach. It offers a valuable resource for statistical analyses of galaxy evolution in the local Universe and for comparisons with existing and future spectroscopic surveys.
