The $\text{NuSTAR}$ Extragalactic Surveys: Source Catalogs from the Extended $\text{Chandra}$ Deep Field-South and the $\text{Chandra}$ Deep Field-North

Abstract

We present a routinized and reliable method to obtain source catalogs from the $\text{Nuclear Spectroscopic Telescope Array}$ ($\text{NuSTAR}$) extragalactic surveys of the Extended $\text{Chandra}$ Deep Field-South (E-CDF-S) and $\text{Chandra}$ Deep Field-North (CDF-N). The $\text{NuSTAR}$ E-CDF-S survey covers a sky area of $\approx 30^{\prime }\times 30^{\prime }$ to a maximum depth of $\sim$ 230 ks corrected for vignetting in the 3--24 keV band, with a total of 58 sources detected in our E-CDF-S catalog; the $\text{NuSTAR}$ CDF-N survey covers a sky area of $\approx 7^{\prime }\times 10^{\prime }$ to a maximum depth of $\sim$ 440 ks corrected for vignetting in the 3--24 keV band, with a total of 42 sources detected in our CDF-N catalog that is produced for the first time. We verify the reliability of our two catalogs by crossmatching them with the relevant catalogs from the $\text{Chandra}$ X-ray observatory, and find that the fluxes of our $\text{NuSTAR}$ sources are generally consistent with that of their $\text{Chandra}$ counterparts. Our two catalogs are produced following the exactly same method and made publicly available, thereby providing a uniform platform that facilitates further studies involving these two fields. Our source-detection method provides a systematic approach for source cataloging in other $\text{NuSTAR}$ extragalactic surveys.
