cds-question@unistra.frgalaxiesinfrared-photometryvisible-astronomybroad-band-photometrystar-forming-regionsWe present model spectral energy distribution (SED) fits to ultraviolet/optical/infrared observations for the 258 nearby galaxies in the Local Volume Legacy survey, a sample dominated by lower-luminosity dwarf irregular systems. The data for each galaxy include up to 26 spatially-integrated broadband and narrowband fluxes from the Galaxy Evolution Explorer, Spitzer Space Telescope, and Infrared Astronomical Satellite space-based platforms, and from the Sloan Digital Sky Survey, Two Micron All Sky Survey, and other ground-based efforts. The CIGALE SED fitting package is employed using a delayed star-formation history with an optional late burst or quenching episode to constrain 11 different free parameters that characterize the properties of each galaxy's stellar and dust emission, with the overriding constraint that the ultraviolet/optical emission absorbed by interstellar dust grains is emitted in equal energy portions at infrared wavelengths. The main results are: (I) 94% of the SED fits yield reduced {chi}2 values less than 3; (II) the modeled stellar masses agree with those derived from 3.6{mu}m-based measures with a scatter of 0.07dex; (III) for a typical galaxy in the sample the SED-derived star-formation rate averaged over the past 100Myr is about 88% of the value derived from standard hybrid indicators on similar timescales; and (IV) there is a statistically significant inverse relation between the stellar mass fraction appearing in the late burst and the total stellar mass. These results build upon prior SED modeling efforts in the local volume and lay the groundwork for future studies of more distant low-metallicity galaxies with JWST.2023AJ....165..260Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/165/260CatalogResearchIsServedByTAP VizieR generic servicerelated-toVII/109 : IRAS Observations of Large Optical Galaxies (Rice+, 1988)J/ApJS/147/29 : BRHa data blue compact dwarf galaxies (Gil De Paz+, 2003)J/AJ/126/1607 : IRAS Revised Bright Galaxy Sample (Sanders+, 2003)J/ApJS/178/247 : H{alpha} and [NII] survey in local 11 Mpc (Kennicutt+, 2008)J/ApJ/703/517 : The Spitzer Local Volume Legacy; IR photometry (Dale+, 2009)J/ApJ/703/1672 : Far-IR and H{alpha} fluxes in galaxies (Kennicutt+, 2009)J/ApJ/706/599 : H{alpha} and UV SFR in the local volume (Lee+, 2009)J/ApJ/714/1256 : Far-IR star formation rate indicators (Calzetti+, 2010)J/ApJ/715/506 : Aromatic inventory of the local volume (Marble+, 2010)J/PASP/122/1397 : Spitzer Survey Stellar Structure in Galaxies (Sheth+, 2010)J/ApJ/723/895 : IR luminosities and aromatic features of 5MUSES (Wu+, 2010)J/ApJS/192/6 : A GALEX UV imaging survey of nearby galaxies (Lee+, 2011)J/ApJ/745/95 : Herschel FIR & submm photo. of KINGFISH sample (Dale+, 2012)J/ApJ/744/44 : H{alpha} and UV fluxes in nearby galaxies (Weisz+, 2012)J/ApJ/779/102 : Metallicities of RGB stars in dwarf galaxies (Kirby+, 2013)J/MNRAS/445/899 : LVL SEDs and physical properties (Cook+, 2014)J/MNRAS/445/881 : LVL global optical photometry (Cook+, 2014)J/A+A/582/A121 : Dust properties in galaxies (Remy-Ruyer+, 2015)J/MNRAS/462/3766 : List of galaxies with star forming regions (Cook+, 2016)J/ApJ/861/94 : SHINING I Survey observational trends (Herrera-Camus+, 2018)J/ApJS/244/24 : z=0 Multiwavelength Galaxy Synthesis.
