cds-question@unistra.frmolecular-cloudschemical-abundancesinterferometryWe present a study with the Plateau de Bure Interferometer of a core in the archetypal filamentary IRDC G11.11-0.12 of a few arcsecond resolution to determine its physical and chemical structures. The data consist of continuum and line observations covering the C^34^S 2-1 line and the methanol 2_k_-1_k_ v_t_=0 lines at 3mm and the methanol 5_k_-4_k_ v_t_=0 lines at1mm. Our observations show extended emission in the continuum at 1 and 3mm. The methanol 2-1 emission has three maxima extending over a 1pc scale (when merged with single-dish short-spacing observations); one of the maxima is spatially coincident with the continuum emission. The fitting results show an enhanced methanol fractional abundance at the central peak with respect to the other two peaks, where it decreases by about an order of magnitude. Wings in the CH_3_OH 2-1 spectra, and CH_3_OH abundance enhancements point to the presence of an outflow in the east-west direction. In addition, we find a gradient of ~4km/s in the same direction, which we interpret as being produced by an outflow(s)-cloud interaction.2011A&A...529A.161Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/529/A161CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/639/227 : MSX IRDC candidate catalog (Simon+, 2006)J/ApJ/641/389 : Millimetric observations of IRDC cores (Rathborne+, 2006)J/ApJ/680/349 : Galactic distribution of IRDCs (Jackson+, 2008)J/ApJ/686/384 : ^12^CO, ^13^CO, C^18^O survey of IRDCs (Du+, 2008)J/A+A/503/859 : IRDC 19175-4 and IRDC 19175-5 turbulence maps (Beuther+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/529/A161https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/529/A161http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/529/A161https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/529/A161https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/529/A161http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/529/A161GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/529/A161/maps (List of the maps (in "figs" subdirectory))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/529/A161/maps?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/529/A161/maps?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/529/A161/maps?GETtext/xml+votable180.050000true272.6177-19.37510.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/529/A1616/29097https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/529/A161?format=asciidefaultJ/A+A/529/A161/mapsList of the maps (in "figs" subdirectory)recnoRecord number assigned by the VizieR team.
