cds-question@unistra.frgalaxy-clustersgalaxiescatalogsspectroscopyWe present the analysis of the emission line galaxies members of 46 low-redshift (0.04<z<0.07) clusters observed by WINGS (WIde-field Nearby Galaxy cluster Survey; Fasano et al., 2006A&A...445..805F). Emission line galaxies were identified following criteria that are meant to minimize biases against non-star-forming galaxies and classified employing diagnostic diagrams. We examined the emission line properties and frequencies of star-forming galaxies, transition objects, and active galactic nuclei (AGNs: LINERs and Seyferts), unclassified galaxies with emission lines, and quiescent galaxies with no detectable line emission. A deficit of emission line galaxies in the cluster environment is indicated by both a lower frequency, and a systematically lower Balmer emission line equivalent width and luminosity with respect to control samples; this implies a lower amount of ionized gas per unit mass and a lower star formation rate if the source is classified as Hii region. A sizable population of transition objects and of low-luminosity LINERs (~10-20% of all emission line galaxies) are detected among WINGS cluster galaxies. These sources are a factor of 1.5 more frequent, or at least as frequent, as in control samples with respect to Hii sources. Transition objects and LINERs in clusters are most affected in terms of line equivalent width by the environment and appear predominantly consistent with so-called retired galaxies. Shock heating can be a possible gas excitation mechanism that is able to account for observed line ratios. Specific to the cluster environment, we suggest interaction between atomic and molecular gas and the intracluster medium as a possible physical cause of line-emitting shocks.2017A&A...599A..83Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/599/A83CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/566/A32 : Equivalent widths of WINGS galaxies (Fritz+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/599/A83https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/599/A83http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/599/A83https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/599/A83https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/599/A83http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/599/A83GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/599/A83/catalog (Emission line catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/599/A83/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/599/A83/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/599/A83/catalog?GETtext/xml+votable180.050000true13.706-1.38858330.0055555555555555565/4504 5120 6159 6/1003-1004 1006 2184 2186 5030-5031 5036 5304-5306 5368 5370 8265 8268 8440 8442 8446 8648-8649 8785 8788 9754 9765 9776 9943 10114 10309 10311 10322 15085 15096 16765-16767 18238 18324 18605 18607 18618 18622-18623 18862 18937 18939 19130 19201 19204 19935 19993 19996 19999 20021 20029 20031 20082-20083 20361 24619 24622 24943 24954 25042-25043 25048 26732 26734 26768 26770-26771 27213 27218 27224 32746 33234-33235 33625 33628 33649-33651 34805 39055 39077 40809 43827-43828 43830 43835 43838 43921 46652-46654 48583 48594 48600https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/599/A83?format=asciidefaultJ/A+A/599/A83/catalogEmission line catalogClassOIClass from [OI] DD (3)meta.code.classcharClassNIIRevRevised class from [NII] DD (4)meta.code.classcharSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
