cds-question@unistra.frplanetary-nebulaephotometrygalaxiesWe report the results of a radial velocity survey of planetary nebulae (PNe) located in the tidal features of the well-known interacting system NGC 5194/95 (M51). We find clear kinematic evidence that M51's northwestern tidal debris consists of two discrete structures that overlap in projection - NGC 5195's own tidal tail and diffuse material stripped from NGC 5194. We compare these kinematic data to a new numerical simulation of the M51 system and show that the data are consistent with the classic "single-passage" model for the encounter, with a parabolic satellite trajectory and a 2:1 mass ratio. We also comment on the spectra of two unusual objects: a high-velocity PN that may be associated with NGC 5194's halo and a possible interloping high-redshift galaxy.2003ApJ...582..170Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/582/170CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/479/231 : PNe in M51, M96 + M101 (Feldmeier+ 1997)J/ApJ/414/454 : NGC 3379 planetary nebulae radial velocities (Ciardullo+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/582/170https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/582/170http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/582/170https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/582/170https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/582/170http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/582/170GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/582/170/table1 (M51 Planetary Nebula Candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/582/170/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/582/170/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/582/170/table1?GETtext/xml+votable180.050000true202.46087547.10763890.0055555555555555566/11026 11027https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/582/170?format=asciiOpticaldefaultJ/ApJ/582/170/table1M51 Planetary Nebula CandidatesrecnoRecord number assigned by the VizieR team.
