cds-question@unistra.frgalaxiessupernova-remnantsWe present results from a study of optically emitting supernova remnants (SNRs) in six nearby galaxies (NGC 2403, 3077, 4214, 4395, 4449 and 5204) based on deep narrow-band H{alpha} and [SII] images as well as spectroscopic observations. The SNR classification was based on the detected sources that fulfil the well-established emission-line flux criterion of [SII]/H{alpha}>0.4. This study revealed ~400 photometric SNRs down to a limiting H{alpha} flux of 10^-15^erg/s/cm^2^. Spectroscopic observations confirmed the shock-excited nature of 56 out of the 96 sources with ([SII]/H{alpha})_phot_>0.3 (our limit for an SNR classification) for which we obtained spectra. 11 more sources were spectroscopically identified as SNRs although their photometric [SII]/H{alpha} ratio was below 0.3. We discuss the properties of the optically detected SNRs in our sample for different types of galaxies and hence different environments, in order to address their connection with the surrounding interstellar medium. We find that there is a difference in [NII]/H{alpha} line ratios of the SNR populations between different types of galaxies which indicates that this happens due to metallicity. We cross-correlate parameters of the optically detected SNRs ([SII]/H{alpha} ratio, luminosity) with parameters of coincident X-ray-emitting SNRs, resulted from our previous studies on the same sample of galaxies, in order to understand their evolution and investigate possible selection effects. We do not find a correlation between their H{alpha} and X-ray luminosities, which we attribute to the presence of material in a wide range of temperatures. We also find evidence for a linear relation between the number of luminous optical SNRs (10^37^erg/s) and star formation rate in our sample of galaxies.2013MNRAS.429..189Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/429/189CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/114/215 : New SNR candidates in M31 (Magnier+, 1995)J/ApJS/120/247 : Supernova remnants in M33 (Gordon+, 1999)J/A+A/435/437 : Extragalactic SNRs brightness and diameters (Urosevic+, 2006)J/AJ/137/3869 : Radio SNRs in 4 irregular galaxies (Chomiuk+, 2009)J/ApJ/703/370 : Radio SNRs in nearby galaxies (Chomiuk+, 2009)J/ApJS/187/495 : SNRs in M33 from optical and X-ray (Long+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/429/189https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/429/189http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/429/189https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/429/189https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/429/189http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/429/189GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/429/189/snr (*Properties of photometric SNRs in NGC 2403, NGC 3077, NGC 4214, NGC 4395, NGC 4449 and NGC 5204 (tables 3-8 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/429/189/snr?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/429/189/snr?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/429/189/snr?GETtext/xml+votable180.050000true114.12666765.5953890.005555555555555556Cone search capability for table J/MNRAS/429/189/non_snr (Photometric and spectroscopic properties of spectroscopically-verified non-SNRs in our sample of galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/429/189/non_snr?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/429/189/non_snr?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/429/189/non_snr?GETtext/xml+votable180.050000true114.05666765.6326390.0055555555555555566/7604 7743 10911 11127 22327 28535 28541 28631https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/429/189?format=asciidefaultJ/MNRAS/429/189/snr*Properties of photometric SNRs in NGC 2403, NGC 3077, NGC 4214, NGC 4395, NGC 4449 and NGC 5204 (tables 3-8 of the paper)recnoRecord number assigned by the VizieR team.
