cds-question@unistra.frinterstellar-mediumco-line-emissionFilaments are a ubiquitous morphological feature of the molecular interstellar medium and are identified as sites of star formation. In recent years, more than 100 large-scale filaments (with length >10pc) have been observed in the inner Milky Way. As they appear linked to Galactic dynamics, studying those structures represents an opportunity to link kpc-scale phenomena to the physics of star formation, which operates on much smaller scales. In this letter, we use newly acquired Outer Galaxy High Resolution Survey (OGHReS) ^12^CO(2-1) data to demonstrate that a significant number of large-scale filaments are present in the outer Galaxy as well. The 37 filaments identified appear tightly associated to inter-arm regions. In addition, their masses and linear masses are, on average, one order of magnitude lower than similar-sized molecular filaments located in the inner Galaxy, showing that Milky Way dynamics is able to create very elongated features in spite of the lower gas supply in the Galactic outskirts.2021A&A...655L...2Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/655/L2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/619/A166 : SEDIGISM, kinematics of ATLASGAL filaments (Mattern+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/655/L2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/655/L2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/655/L2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/655/L2https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/655/L2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/655/L2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/655/L2/list (List of fits datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/655/L2/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/655/L2/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/655/L2/list?GETtext/xml+votable180.050000true120.4943536-33.90075790.0055555555555555566/37371 37713 37715 37744 37746-37747 37752 37754 37831 37839-37840 37848 37850 37869 37874 39245 39269-39271 39276 39278 39364 39366 39375 39406https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/655/L2?format=asciiRadiodefaultJ/A+A/655/L2/listList of fits datacubesrecnoRecord number assigned by the VizieR team.
