Our revised catalog of SNR candidates in M83 has 366 objects, 81 of which are reported here for the first time. Of these, 229 lie within the MUSE observation region, 160 of which have spectra with [SII]:H{alpha} ratios exceeding 0.4, the value generally accepted as confirmation that an emission nebula is shock-heated. Combined with 51 SNR candidates outside the MUSE region with high [SII]:H{alpha} ratios, there are 211 spectroscopically confirmed SNRs in M83, the largest number of confirmed SNRs in any external galaxy. MUSE's combination of relatively high spectral resolution and broad wavelength coverage has allowed us to explore two other properties of SNRs that could serve as the basis of future SNR searches. Specifically, most of the objects identified as SNRs on the basis of [SII]:H{alpha} ratios exhibit more velocity broadening and lower ratios of [SIII]:[SII] emission than HII regions. A search for nebulae with the very broad emission lines expected from young, rapidly expanding remnants revealed none, except for the previously identified B12-174a. The SNRs identified in M83 are, with few exceptions, middle-aged interstellar medium (ISM) dominated ones. Smaller-diameter candidates show a larger range of velocity broadening and a larger range of gas densities than the larger-diameter objects, as expected if the SNRs expanding into denser gas brighten and then fade from view at smaller diameters than those expanding into a more tenuous ISM.2022ApJ...929..144Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/929/144CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/138/332 : LEDA CMD/tip of the red giant branch (Jacobs+, 2009)J/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 spectroscopic obs. of SNR cand. 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/MNRAS/495/479 : New radio catalog for M83 SNR & HII regions (Russell+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/929/144https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/929/144http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/929/144https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/929/144https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/929/144http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/929/144GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/929/144/table1 (Supernova remnants and candidates in M83)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/929/144/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/929/144/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/929/144/table1?GETtext/xml+votable180.050000true204.16663-29.859760.005555555555555556Cone search capability for table J/ApJ/929/144/hiireg (HII regions in M83 (Table 3) with MUSE spectra data (Table 4))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/929/144/hiireg?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/929/144/hiireg?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/929/144/hiireg?GETtext/xml+votable180.050000true204.2098-29.859760.0055555555555555566/43881https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/929/144?format=asciiX-rayOpticaldefaultJ/ApJ/929/144/table1Supernova remnants and candidates in M83recnoRecord number assigned by the VizieR team.
