cds-question@unistra.frmolecular-cloudsyoung-stellar-objectspolarimetryinterstellar-mediuminfrared-photometryWe present the results of near-infrared (NIR) linear imaging polarimetry in the J, H, and Ks bands of the low-mass star cluster-forming region in the Circinus Molecular Cloud Complex. Using aperture polarimetry of point-like sources, positive detection of 314, 421, and 164 sources in the J, H, and Ks bands, respectively, was determined from among 749 sources whose photometric magnitudes were measured. For the source classification of the 133 point-like sources whose polarization could be measured in all 3 bands, a color-color diagram was used. While most of the NIR polarizations of point-like sources are well-aligned and can be explained by dichroic polarization produced by aligned interstellar dust grains in the cloud, 123 highly polarized sources have also been identified with some criteria. The projected direction on the sky of the magnetic field in the Cir-MMS region is indicated by the mean polarization position angles (70{deg}) of the point-like sources in the observed region, corresponding to approximately 1.6x1.6pc^2^. In addition, the magnetic field direction is compared with the outflow orientations associated with Infrared Astronomy Satellite sources, in which two sources were found to be aligned with each other and one source was not. We also show prominent polarization nebulosities over the Cir-MMS region for the first time. Our polarization data have revealed one clear infrared reflection nebula (IRN) and several candidate IRNe in the Cir-MMS field. In addition, the illuminating sources of the IRNe are identified with near- and mid-infrared sources.2018ApJS..234...42Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/234/42CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/136/621 : Near-infrared polarimetry of M42 (Kusakabe+, 2008)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/733/L2 : YSOs from WISE in Western Circinus cloud (Liu+, 2011)J/ApJ/743/54 : Polarization around star-forming regions (Targon+, 2011)J/ApJS/220/17 : Wide-field NIR polarimetry of {rho} Oph cloud (Kwon+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/234/42https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/234/42http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/234/42https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/234/42https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/234/42http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/234/42GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/234/42/table1 (Photometry and polarimetry of point-like sources in the Circinus Molecular Cloud Complex)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/234/42/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/234/42/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/234/42/table1?GETtext/xml+votable180.050000true225.0377917-63.17994440.005555555555555556Cone search capability for table J/ApJS/234/42/table2 (Polarizations of additional sources detected in the J and H bands)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/234/42/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/234/42/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/234/42/table2?GETtext/xml+votable180.050000true225.0359583-63.17697220.005555555555555556Cone search capability for table J/ApJS/234/42/table3 (Polarizations of additional sources detected in the H and K_s_ bands)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/234/42/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/234/42/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/234/42/table3?GETtext/xml+votable180.050000true225.0924583-63.18063890.005555555555555556Cone search capability for table J/ApJS/234/42/table4 (Polarization degrees and polarization position angles of highly polarized sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/234/42/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/234/42/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/234/42/table4?GETtext/xml+votable180.050000true225.0157083-63.17430560.0055555555555555566/417407.952274030004205e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/234/42?format=asciiInfrareddefaultJ/ApJS/234/42/table1Photometry and polarimetry of point-like sources in the Circinus Molecular Cloud ComplexrecnoRecord number assigned by the VizieR team.
