GalEffNet Predicted Stellar Mass and sSFR Catalog from DESI DR9
Li-Li Wang ; Jia-Bao feng
This catalog is constructed from galaxies selected from the DESI Legacy Imaging Surveys DR9, applying criteria of redshift z < 0.3 and z-band magnitude mag_z < 21. For each galaxy, we provide deep learning–based predictions of stellar mass (M*) and specific star formation rate (sSFR) using our GalEffNet model, along with basic photometric and morphological information. The catalog is designed to facilitate studies of galaxy properties and evolutionary trends at low redshift.
Column descriptions:
release: Camera and filter set identifier from DESI-LIS DR9.
brickid: Unique Brick ID from DESI-LIS DR9.
objid: Object number within a given brick.
ra, dec: Right ascension and declination (J2000).
source_type: Morphological type, one of {DEV, SER, REX, EXP}.
z_phot: Photometric redshift from Zhou et al. (2021).
mag_g, mag_r, mag_z: Magnitudes in the g, r, and z bands, converted from DR9 fluxes.
pred_mass: Stellar mass, predicted by GalEffNet.
pred_ssfr: Specific star formation rate, predicted by GalEffNet.
