Abstract:
We 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 χ2 values less than 3; (II) the
modeled stellar masses agree with those derived from 3.6µm-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.
Description:
The Local Volume Legacy (LVL) broadband data sets used in this work
include GALEX ultraviolet, 2MASS near-infrared, and Spitzer infrared
imaging. We have supplemented these data sets with global IRAS
infrared flux densities.
Filter band details are available in table1.

Note on table4.dat: Upper limits for non-detections. No color
corrections have been applied. The filter central wavelengths and
widths are computed via Equations 1 and 2 of Dale+, 2017ApJ...837...90D 2017ApJ...837...90D.
Note that the Spitzer MIPS data for NGC3034 suffer from saturation and
thus the tabulated values are lower limits.
