cds-question@unistra.frgalaxiesinfrared-astronomyspectroscopyWe present resolved [CI] line intensities of 18 nearby galaxies observed with the SPIRE FTS spectrometer on the Herschel Space Observatory. We use these data along with resolved CO line intensities from J_up_=1 to 7 to interpret what phase of the interstellar medium the [CI] lines trace within typical local galaxies. A tight, linear relation is found between the intensities of the CO(4-3) and [CI](2-1) lines; we hypothesize this is due to the similar upper level temperature of these two lines. We modeled the [CI] and CO line emission using large-velocity gradient models combined with an empirical template. According to this modeling, the [CI](1-0) line is clearly dominated by the low-excitation component. We determine [CI] to molecular mass conversion factors for both the [CI](1-0) and [CI](2-1) lines, with mean values of {alpha}_[CI](1-0)_=7.3M_{sun}_/K/km.s/pc^2^ and {alpha}_[CI](2-1)_=34M_{sun}_/K/km.s/pc^2^ with logarithmic root-mean-square spreads of 0.20 and 0.32dex, respectively. The similar spread of {alpha}_[CI](1-0)_ to {alpha}_CO_ (derived using the CO(2-1) line) suggests that [CI](1-0) may be just as good a tracer of cold molecular gas as CO(2-1) in galaxies of this type. On the other hand, the wider spread of {alpha}_[CI](2-1)_ and the tight relation found between [CI](2-1) and CO(4-3) suggest that much of the [CI](2-1) emission may originate in warmer molecular gas.2019ApJ...887..105Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/887/105CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/190/233 : Spectroscopy & abundances of SINGS galaxies (Moustakas+, 2010)J/ApJ/745/95 : Herschel FIR & submm phot. of KINGFISH sample (Dale+, 2012)J/A+A/576/A33 : KINGFISH galaxy sample radial profile SED (Hunt+, 2015)J/ApJ/829/93 : CO, [CI] & [NII] lines from Herschel (Kamenetzky+, 2016)J/ApJS/230/1 : Herschel SPIRE/FTS 194-671um survey of GOALS LIRGs (Lu+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/887/105https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/887/105http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/887/105https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/887/105https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/887/105http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/887/105GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/887/105/table1 (Beyond the Peak (BtP) galaxies: basic parameters and coverage)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/887/105/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/887/105/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/887/105/table1?GETtext/xml+votable180.050000true54.1628208-20.90226110.005555555555555556Cone search capability for table J/ApJ/887/105/table2 ([CI](1-0) and [CI](2-1) line intensities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/887/105/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/887/105/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/887/105/table2?GETtext/xml+votable180.050000true41.58504-30.269980.0055555555555555566/5799 7602 7604 10761 10841 10856 11434 13522 15592 15593 23178 25946 26271 27030 27514 27861 27937 28015 28033 28035 28167 35993 36194 36241https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/887/105?format=asciiInfrareddefaultJ/ApJ/887/105/table1Beyond the Peak (BtP) galaxies: basic parameters and coveragerecnoRecord number assigned by the VizieR team.
