cds-question@unistra.frsupernova-remnantsvisible-astronomyspectroscopystellar-radiiIn order to better characterize the rich supernova remnant (SNR) population of M83 (NGC 5236), we have obtained high-resolution (~85km/s) spectra of 119 of the SNRs and SNR candidates in M83 with Gemini/GMOS, as well as new spectra of the young SNRs B12-174a and SN1957D. Most of the SNRs and SNR candidates have [SII]:H{alpha} ratios that exceed 0.4. Combining these results with earlier studies we have carried out with MUSE and at lower spectroscopic resolution with GMOS, we have confirmed a total of 238 emission nebulae to be SNRs on the basis of their [SII]:H{alpha} ratios, about half of which have emission lines that show velocity broadening greater than 100km/s, providing a kinematic confirmation that they are SNRs and not HII regions. Looking at the entire sample, we find a strong correlation between velocity widths and the line ratios of [OI]{lambda}6300:H{alpha}, [NII]{lambda}6584:H{alpha}, and [SII]{lambda}{lambda}6716,6731:H{alpha}. The density-sensitive [SII]{lambda}6716:{lambda}6731 line ratio is strongly correlated with SNR diameter, but not with the velocity width. We discuss these results in the context of previously published shock models.2023ApJ...943...15Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/943/15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/203/8 : Optical SNR candidates in M83 (Blair+, 2012)J/ApJ/788/55 : HST/WFC3 SNR discoveries in M83 (NGC5236) (Blair+, 2014)J/ApJS/212/21 : A deep Chandra ACIS survey of M83 (Long+, 2014)J/ApJ/839/83 : GMOS sp. obs. of SNR candidates in M83 (Winkler+, 2017)J/ApJ/855/140 : MMT spectra of SNRs and SNR candidates in M33 (Long+, 2018)J/ApJ/881/54 : Masses of SNR progenitors in M83 (Williams+, 2019)J/ApJ/899/14 : Opt. & FeII sources in SNR with HST (Long+, 2020)J/MNRAS/508/5425 : Study of NGC 300 objects with dendogram (McLeod+, 2021)J/ApJ/929/144 : SNR and HII regions in M83 observed with MUSE (Long+, 2022)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/943/15https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/943/15http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/943/15https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/943/15https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/943/15http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/943/15GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/943/15/table5 (Properties of supernova remnants and candidates in M83)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/943/15/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/943/15/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/943/15/table5?GETtext/xml+votable180.050000true204.16663-29.859760.0055555555555555566/43881https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/943/15?format=asciiOpticaldefaultJ/ApJ/943/15/table5Properties of supernova remnants and candidates in M83FeIIIn HST F164N [FeII] imagery?
