cds-question@unistra.frgalaxiesinfrared-sourcesinfrared-astronomyspectroscopyWe present the data and our analysis of mid-infrared atomic fine-structure emission lines detected in Spitzer/Infrared Spectrograph high-resolution spectra of 202 local Luminous Infrared Galaxies (LIRGs) observed as part of the Great Observatories All-sky LIRG Survey (GOALS). We readily detect emission lines of [SIV], [NeII], [NeV], [NeIII], [SIII]_18.7{mu}m_, [OIV], [FeII], [SIII]_33.5{mu}m_, and [SiII]. More than 75% of these galaxies are classified as starburst-dominated sources in the mid-infrared, based on the [NeV]/[NeII] line flux ratios and equivalent width of the 6.2{mu}m polycyclic aromatic hydrocarbon feature. We compare ratios of the emission-line fluxes to those predicted from stellar photo-ionization and shock-ionization models to constrain the physical and chemical properties of the gas in the starburst LIRG nuclei. Comparing the [SIV]/[NeII] and [NeIII]/[NeII] line ratios to the Starburst99-Mappings III models with an instantaneous burst history, the emission-line ratios suggest that the nuclear starbursts in our LIRGs have ages of 1-4.5 Myr, metallicities of 1-2Z_{sun}_, and ionization parameters of 2-8x10^7^cm/s. Based on the [SIII]_33.5{mu}m_/[SIII]_18.7{mu}m_ ratios, the electron density in LIRG nuclei is typically one to a few hundred/cm3, with a median electron density of ~300/cm3, for those sources above the low density limit for these lines.2013ApJ...777..156Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/777/156CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/206/1 : Mid-IR properties of GOALS nearby LIRGs (Stierwalt+, 2013)J/ApJ/774/68 : [CII]157.7um spectroscopic obs. of LIRGs (Diaz-Santos+, 2013)J/ApJS/203/3 : Spectroscopy of 39 IRAS 1Jy sample ULIRG (Soto+, 2012)J/ApJ/741/32 : Spatial extent of LIRGs in the MIR.
