cds-question@unistra.frgalaxiesinfrared-sourcesinterstellar-mediumspectroscopyWe present Herschel PACS spectroscopic observations of the [CII] 157um, [OI] 63 and 145um, [OIII] 88um, [NII] 122 and 205um, and [NIII] 57um fine-structure cooling lines in a sample of 48 low-metallicity star-forming galaxies of the guaranteed time key program Dwarf Galaxy Survey. We correlate PACS line ratios and line-to-LTIR ratios with LTIR, LTIR/LB, metallicity, and FIR color, and interpret the observed trends in terms of ISM conditions and phase filling factors with Cloudy radiative transfer models. We find that the ISM of low-metallicity dwarf galaxies has a more porous structure than that of metal-rich galaxies. The radiation fields are harder and the the ionized gas/PDR filling factor is larger in the dwarfs.2015A&A...578A..53Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/578/A53CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/578/A53https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/578/A53http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/578/A53https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/578/A53https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/578/A53http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/578/A53GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/578/A53/compact (Far-IR line fluxes and luminosities of the compact sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/578/A53/compact?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/578/A53/compact?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/578/A53/compact?GETtext/xml+votable180.050000true9.219583-33.5547220.005555555555555556Cone search capability for table J/A+A/578/A53/extended (Far-IR line fluxes and luminosities of the extended sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/578/A53/extended?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/578/A53/extended?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/578/A53/extended?GETtext/xml+votable180.050000true5.1087559.2883330.005555555555555556Cone search capability for table J/A+A/578/A53/tablea1 (Technical details about the DGS observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/578/A53/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/578/A53/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/578/A53/tablea1?GETtext/xml+votable180.050000true9.21875-33.55527780.0055555555555555566/3042 3389 5950 6011 6042 6046 6419 7281 7878 7946 8028 10399 10431 10481 10587 10689 10769 10811 10881 10911 10970 11137 11177-11178 11382 18002 18198 19570 19934 20283 20388 22828 23078 23566 24696 25594 25659 26971 28631 29718 33091 33094 33126 33317 33986 35243 35576 36756 40124 43874https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/578/A53?format=asciiInfrareddefaultJ/A+A/578/A53/tablec1Low-resolution MIR line fluxes in the compact galaxies of the DGSl_F36.0[<= ] Limit flag on F36.0 (2{sigma})meta.code.errorrecnoRecord number assigned by the VizieR team.
