cds-question@unistra.frinterstellar-mediummolecular-cloudsMapping of the near-infrared (NIR) scattered light is a recent method for the study of interstellar clouds, complementing other, more commonly used methods, like dust emission and extinction. Our goal is to study the usability of this method on larger scale, and compare the properties of a filamentary structure using infrared scattering and other methods. We also study the radiation field and differences in grain emissivity between diffuse and dense areas. We have used scattered NIR J, H, and K band surface brightness observations with WFCAM instrument to map a filament TMC-1N in Taurus Molecular Cloud, covering an area of 1{deg}x1{deg} corresponding to ~(2.44pc). We have converted the data into an optical depth map and compared the results with NIR extinction and Herschel observations of sub-mm dust emission. We have also modelled the filament with 3D radiative transfer calculations of scattered light.2013A&A...558A..44Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/558/A44CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/558/A44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/558/A44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/558/A44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/558/A44https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/558/A44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/558/A44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/558/A44/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/558/A44/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/558/A44/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/558/A44/list?GETtext/xml+votable180.050000true69.8844826.616860.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/558/A446/1055https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/558/A44?format=asciidefaultJ/A+A/558/A44/listList of fits filesrecnoRecord number assigned by the VizieR team.
