cds-question@unistra.frinterstellar-mediumradio-astronomygalaxy-planesmilky-way-galaxyh-i-line-emissionWe present the results of a search for faint HI 21cm emission line wings at velocities forbidden by Galactic rotation in the Galactic plane using the Leiden/Dwingeloo HI Survey data and the HI Southern Galactic Plane Survey data. These "forbidden-velocity wings" (FVWs) appear as protruding excessive emission in comparison with their surroundings in limited (>~2{deg}) spatial regions over velocity extents of more than ~20km/s in large-scale (l,v) diagrams. Their high velocities imply that there should be some dynamical phenomena associated. We have identified 87 FVWs. We present their catalog and discuss their distribution and statistical properties. We found that 85% of FVWs are not coincident with known supernova remnants (SNRs), galaxies, or high-velocity clouds. Their natures are currently unknown.2007ApJS..173...85Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/173/85CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/73 : HI Parkes All Sky Survey Catalogue (HIPASS) (Meyer+, 2004)J/A+A/391/159 : A search for Compact High-Velocity Clouds (De Heij+, 2002)J/A+AS/83/539 : 21cm radio continuum survey.
