By complementing these observations with new polarization observations from the Submillimeter Array (SMA) and archival data from the Combined Array for Research in Millimeter- wave Astronomy (CARMA) and the James Clerk Maxwell Telescopes (JCMT), we can compare the magnetic field orientations at different spatial scales. We find major changes in the magnetic field orientation between large (~0.1pc) scales-where the magnetic field is oriented E-W, perpendicular to the major axis of the dusty filament where SMM1 is embedded-and the intermediate and small scales probed by CARMA (~1000au resolution), the SMA (~350au resolution), and ALMA (~140au resolution). The ALMA maps reveal that the redshifted lobe of the bipolar outflow is shaping the magnetic field in SMM1 on the southeast side of the source; however, on the northwestern side and elsewhere in the source, low-velocity shocks may be causing the observed chaotic magnetic field pattern. High-spatial-resolution continuum and spectral-line observations also reveal a tight (~130au) protobinary system in SMM1-b, the eastern component of which is launching an extremely high-velocity, one-sided jet visible in both CO(J=2->1) and SiO(J=5->4); however, that jet does not appear to be shaping the magnetic field. These observations show that with the sensitivity and resolution of ALMA, we can now begin to understand the role that feedback (e.g., from protostellar outflows) plays in shaping the magnetic field in very young, star-forming sources like SMM1.2017ApJ...847...92Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/847/92CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/707/103 : Observation of Ser FIRS 1 at 230GHz (Enoch+, 2009)J/A+A/563/L3 : NGC1333-IRAS2A CALYPSO IRAM-PdBI SiO & SO maps (Codella+, 2014)J/ApJ/783/6 : Deconvolved Spitzer images of 89 protostars (Velusamy+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/847/92https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/847/92http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/847/92https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/847/92https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/847/92http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/847/92GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/847/92/table1 (SMM1 source properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/847/92/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/847/92/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/847/92/table1?GETtext/xml+votable180.050000true277.45754171.25566940.005555555555555556Cone search capability for table J/ApJ/847/92/table3 (ALMA polarization data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/847/92/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/847/92/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/847/92/table3?GETtext/xml+votable180.050000true277.458681.254240.0055555555555555566/30366https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/847/92?format=asciiRadiodefaultJ/ApJ/847/92/table1SMM1 source propertiesrecnoRecord number assigned by the VizieR team.
