cds-question@unistra.frpolarimetrymillimeter-astronomysubmillimeter-astronomymolecular-cloudsinterstellar-mediumWe present 850{mu}m imaging polarimetry data of the {rho} Oph-A core taken with the Submillimeter Common-User Bolometer Array-2 (SCUBA-2) and its polarimeter (POL-2) as part of our ongoing survey project, B-fields In STar forming RegiOns (BISTRO). The polarization vectors are used to identify the orientation of the magnetic field projected on the plane of the sky at a resolution of 0.01pc. We identify 10 subregions with distinct polarization fractions and angles in the 0.2pc {rho} Oph-A core; some of them can be part of a coherent magnetic field structure in the {rho} Oph region. The results are consistent with previous observations of the brightest regions of {rho} Oph-A, where the degrees of polarization are at a level of a few percent, but our data reveal for the first time the magnetic field structures in the fainter regions surrounding the core where the degree of polarization is much higher (>5%). A comparison with previous near-infrared polarimetric data shows that there are several magnetic field components that are consistent at near-infrared and submillimeter wavelengths. Using the Davis-Chandrasekhar-Fermi method, we also derive magnetic field strengths in several subcore regions, which range from approximately 0.2 to 5mG. We also find a correlation between the magnetic field orientations projected on the sky and the core centroid velocity components.2018ApJ...859....4Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/859/4CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/216/44 : Walraven photometry in Sco-Cen association (De Geus+, 1989)J/ApJ/650/945 : Polarisation around filamentary dark cloud GF 9J/A+A/472/519 : N2H+(1-0) maps of Ophiuchus main cloud (Andre+, 2007)J/ApJS/181/321 : Properties of Spitzer c2d dark clouds (Evans+, 2009)J/ApJS/182/143 : SCUPOL Legacy polarimetry of SCUBA (Matthews+, 2009)J/A+A/498/167 : Embedded sources in L 1688 (van Kempen+, 2009)J/ApJS/186/406 : 350um polarimetry from CSO (Dotson+, 2010)J/ApJ/708/758 : Polarimetry of HH1-2 region (Kwon+, 2010)J/ApJ/741/35 : NIR photometry and polarization in NGC 2264 (Kwon+, 2011)J/ApJ/793/126 : L204 - Cloud 3 polarimetry and photometry (Cashman+, 2014)J/ApJ/783/1 : VRI and H polarization toward Sh 2-29 (Santos+, 2014)J/ApJS/220/17 : Wide-field NIR polarimetry of {rho} Oph cloud (Kwon+, 2015)J/MNRAS/447/1996 : Ophiuchus molecular cloud CO observations (White+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/859/4https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/859/4http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/859/4https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/859/4https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/859/4http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/859/4GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/859/4/table1 (Submillimeter polarimetry in the {rho} Ophiuchi cloud core)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/859/4/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/859/4/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/859/4/table1?GETtext/xml+votable180.050000true246.639167-24.4430830.0055555555555555566/42981https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/859/4?format=asciiMillimeterdefaultJ/ApJ/859/4/table1Submillimeter polarimetry in the {rho} Ophiuchi cloud corerecnoRecord number assigned by the VizieR team.
