cds-question@unistra.frgalaxiesinfrared-sourcesinterstellar-mediumspectroscopyastronomical-modelsWe employ a multiphase approach to model the ISM phases of the galaxies from the Herschel Dwarf Galaxy Survey with the spectral synthesis code Cloudy. We characterize the physical conditions (gas densities, radiation fields, porosity) in those galaxies and investigate correlations with metallicity or star-formation activity. We find that the lower-metallicity galaxies tend to have higher ionization parameters and galaxies with higher specific star-formation rates have higher gas densities. The [CII] emission arises mainly from PDRs and the contribution from the ionized gas phases is small, typically less than 30% of the observed emission. We also find a correlation, with scatter, between metallicity and both the PDR covering factor and the fraction of [CII] from the ionized gas. Overall, the low metal abundances appear to be driving most of the changes in the ISM structure and conditions of these galaxies, and not the high specific star-formation rates. These results demonstrate in a quantitative way the increase of ISM porosity at low metallicity.2019A&A...626A..23Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/626/A23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/582/A121 : Dust properties in galaxies (Remy-Ruyer+, 2015)J/A+A/578/A53 : Spectroscopy of Herschel Dwarf Galaxy Survey (Cormier+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/626/A23https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/626/A23http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/626/A23https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/626/A23https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/626/A23http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/626/A23GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/626/A23/obs (Observed MIR and FIR line fluxes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/626/A23/obs?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/626/A23/obs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/626/A23/obs?GETtext/xml+votable180.050000true158.1331554.40098060.0055555555555555566/3389 5950 6011 6042 6046 6419 7281 7946 8028 10399 10431 10481 10587 10689 10811 10881 10970 11137 11177-11178 11382 18002 18198 19570 19934 20283 20388 22828 23078 23566 24696 25594 25659 26971 28631 33986 35243 35576 36756 40124 43874https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/626/A23?format=asciiInfrareddefaultJ/A+A/626/A23/obsObserved MIR and FIR line fluxesSimbadNameSimbad column added by the CDSmeta.idcharl_H2S1[-] - for 1-sigma upper limitmeta.code.errorcharrecnoRecord number assigned by the VizieR team.
