Stellar Masses and Star-Formation Rates of Galaxies and AGNs in the eFEDS GAMA09 Field

The eFEDS is a wide ≈ 140 deg² field that has extensive multiwavelength coverage. To improve the utility of the existing data, we use CIGALE to fit source Spectral Energy Distributions (SEDs) from X-rays to far-infrared (FIR) mainly to derive stellar masses (M*) and star-formation rates (SFRs) for normal galaxies and X-ray Active Galactic Nuclei (AGNs). The catalog consists of 2057027 galaxies and 10373 X-ray AGNs located in the ≈ 60 deg² GAMA09 sub-field. Comparing our M* with other available catalogs and our SFRs with FIR-derived SFRs, we demonstrate the general reliability of our SED-fitting measurements. Our catalog is publicly available at 10.5281/zenodo.10127224.
