Stellar Mass and Emission Line Catalog¶

Overview¶

This catalog provides the stellar mass and emission line measurements for all galaxies in DESI DR1 with reliable redshift measurements. Stellar mass is dervied by using CIGALE, which employs the broad-band g, r, z, W1, and W2 photometry from the DESI Legacy Imaging Surveys, and spectrophotometry of 10 artificial bands generated through convolution with DESI spectra. Main optical emission lines are measured by a single Gaussian fit, with absorption correction through continuum fitting performed by STARLIGHT. Additionally, the catalog includes stellar population properties derived by CIGALE and those obtained by STARLIGHT using DESI spectra. For additional information see Zou Hu et al. (2024) and Zou Hu et al. (2025) in preparation.

Documentation¶

Files¶

dr1_galaxy_stellarmass_lineinfo_v1.0.fits: Stellar mass and emission line information for all galaxies with reliable redshift measurements in DESI DR1, defined as SPECTYPE==GALAXY and ZWARN==0. Some of the photometric content for each object is also included (refer to the Legacy Surveys website for more information). Note that the quantities of the emission lines are measured from the rest-frame spectra. We recommend using the stellar mass obtained from CIGALE (MASS_CG). Additionally, the stellar population properties, such as age and metallicity, for the DESI BGS sample, are more accurately derived by STARLIGHT using DESI spectra compared to those obtained by CIGALE from multi-wavelength photometry.

Data model¶

The following data model is grouped by data source, and thus does not match exactly the order of columns in the VAC. All data is contained in the single binary table HDU EMLINES_MASS.
