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

Abstract The eFEDS is a wide ≈140 deg 2 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...

Summary:Abstract The eFEDS is a wide ≈140 deg 2 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 2,057,027 galaxies and 10,373 X-ray AGNs located in the ≈60 deg 2 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 in Zenodo.
