Wide Chandra Deep Field South (W-CDFS) in S-band (2\u20134 GHz). Our W-CDFS image has an angular resolution of 15 arcsec and a 1\u03c3 RMS in Stokes I of \u224850 \u03bcJy\/beam. We detect 1920 distinct source components in Stokes I and 175 in linear polarization. We examine the polarized source counts, Faraday Rotation measures, and fractional polarization of the sources in the survey. We show that sources with a total intensity above \u224810 mJy have a mean fractional polarization value of \u22483% from modeling the polarized counts. We also calculate an estimate for the limit on the fractional polarization level of sources with a total intensity below 1 mJy (mostly star-forming galaxies) of \u22723% using stacking. The mean Faraday Rotation we measure is consistent with that due to the Milky Way. We also show that fractional polarization is correlated with in-band spectral index, consistent with a lower mean fractional polarization for the flat-spectrum population. In addition to characterizing the S-band polarization properties of sources in the W-CDFS, this study will be used to validate the shallower, but higher angular resolution S-band polarimetric information that the VLA Sky Survey will provide for the whole sky above Declination \u221240 degrees over the next few years.<\/jats:p>","DOI":"10.3390\/universe12020038","type":"journal-article","created":{"date-parts":[[2026,1,28]],"date-time":"2026-01-28T15:56:12Z","timestamp":1769615772000},"page":"38","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Properties of Polarized Radio Sources in the Wide Chandra Deep Field South from 2 to 4 GHz"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-6268-660X","authenticated-orcid":false,"given":"Samantha","family":"Adams","sequence":"first","affiliation":[{"name":"Department of Physics, University of Connecticut, Unit 3046, 196 Auditorium Road, Storrs, CT 06269, USA"},{"name":"National Radio Astronomy Observatory, Charlottesville, VA 22903, USA"},{"name":"Department of Physics, University of Rhode Island, Kingston, RI 02881, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3032-1783","authenticated-orcid":false,"given":"Mark","family":"Lacy","sequence":"additional","affiliation":[{"name":"National Radio Astronomy Observatory, Charlottesville, VA 22903, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5825-9635","authenticated-orcid":false,"given":"Preshanth","family":"Jagannathan","sequence":"additional","affiliation":[{"name":"National Radio Astronomy Observatory, Socorro, NM 87801, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9149-2973","authenticated-orcid":false,"given":"Jose","family":"Afonso","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Lisbon, 1749-016 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0167-2453","authenticated-orcid":false,"given":"William Nielsen","family":"Brandt","sequence":"additional","affiliation":[{"name":"Department of Astronomy and Astrophysics, The Pennsylvania State University, University Park, PA 16802, USA"},{"name":"Institute for Gravitation and the Cosmos, The Pennsylvania State University, University Park, PA 16802, USA"},{"name":"Department of Physics, 104 Davey Lab, The Pennsylvania State University, University Park, PA 16802, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3382-9558","authenticated-orcid":false,"given":"B.
