cds-question@unistra.frinfrared-photometrypolarimetrymagellanic-cloudsproper-motionsvisible-astronomybroad-band-photometryWe present a near-infrared band-merged photometric and polarimetric catalog for the 39'x69' fields in the northeastern part of the Large Magellanic Cloud (LMC), which were observed using SIRPOL, an imaging polarimeter of the InfraRed Survey Facility. This catalog lists 1858 sources brighter than 14mag in the H band with a polarization signal-to-noise ratio greater than three in the J, H, or K_s_ bands. Based on the relationship between the extinction and the polarization degree, we argue that the polarization mostly arises from dichroic extinctions caused by local interstellar dust in the LMC. This catalog allows us to map polarization structures to examine the global geometry of the local magnetic field, and to show a statistical analysis of the polarization of each field to understand its polarization properties. In the selected fields with coherent polarization position angles, we estimate magnetic field strengths in the range of 3-25{mu}G using the Chandrasekhar-Fermi method. This implies the presence of large-scale magnetic fields on a scale of around 100 parsecs. When comparing mid- and far-infrared dust emission maps, we confirmed that the polarization patterns are well aligned with molecular clouds around the star-forming regions.2016ApJS..222....2Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/222/2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/320 : SPM 4.0 Catalog (Girard+, 2011)II/288 : IRSF Magellanic Clouds Point Source Catalog (Kato+ 2007)J/AJ/144/179 : AKARI-LMC Point-source catalog (Kato+, 2012)J/ApJ/759/25 : Rotation measures at 1.4GHz toward the LMC (Mao+, 2012)J/ApJ/741/21 : Polarization of stars in Taurus (Chapman+, 2011)J/ApJS/178/56 : CO observations of LMC Giant Molecular clouds (Fukui+, 2008)J/ApJS/171/419 : Catalog of LMC HI clouds (Kim+, 2007)J/AJ/132/2268 : SAGE calibration stars (Meixner+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/222/2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/222/2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/222/2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/222/2https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/222/2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/222/2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/222/2/table2 (Photometric and polarimetric catalog of the sources on the northeastern regions in the LMC)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/222/2/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/222/2/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/222/2/table2?GETtext/xml+votable180.050000true84.93476111-69.044036940.0055555555555555566/33091 33094 330953.322582951404819e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/222/2?format=asciiInfraredOpticaldefaultJ/ApJS/222/2/table2Photometric and polarimetric catalog of the sources on the northeastern regions in the LMCrecnoRecord number assigned by the VizieR team.
