Abstract:
We present an atlas of 129 spectral energy distributions for nearby
galaxies, with wavelength coverage spanning from the ultraviolet to
the mid-infrared. Our atlas spans a broad range of galaxy types,
including ellipticals, spirals, merging galaxies, blue compact dwarfs,
and luminous infrared galaxies. We have combined ground-based optical
drift-scan spectrophotometry with infrared spectroscopy from Spitzer
and Akari with gaps in spectral coverage being filled using
Multi-wavelength Analysis of Galaxy Physical Properties spectral
energy distribution models. The spectroscopy and models were
normalized, constrained, and verified with matched-aperture photometry
measured from Swift, Galaxy Evolution Explorer, Sloan Digital Sky
Survey, Two Micron All Sky Survey, Spitzer, and Wide-field Infrared
Space Explorer images. The availability of 26 photometric bands
allowed us to identify and mitigate systematic errors present in the
data. Comparison of our spectral energy distributions with other
template libraries and the observed colors of galaxies indicates that
we have smaller systematic errors than existing atlases, while
spanning a broader range of galaxy types. Relative to the prior
literature, our atlas will provide improved K-corrections, photometric
redshifts, and star-formation rate calibrations.
Description:
Our sample consists of z<0.05 galaxies with archival drift-scan
optical spectroscopy, all of which have well calibrated
multi-wavelength imaging spanning from the ultraviolet to the
mid-infrared. Almost all galaxies in our sample have spectra from the
Spitzer Space Telescope's Infrared Spectrograph (IRS), with the
exceptions being elliptical galaxies with (approximately)
Rayleigh-Jeans spectra in the mid-infrared. The bulk of the optical
spectra are taken from Moustakas & Kennicutt (2006, Cat. J/ApJS/164/81)
and Moustakas et al. (2010, Cat. J/ApJS/190/233), who used the Bok
2.3m and CTIO 1.5m telescopes, with some additional spectra of
elliptical galaxies taken from Kennicutt (1992, Cat. VII/141) and
Gavazzi et al. (2004, Cat. J/A+A/417/499). Akari Infrared Camera (IRC)
spectroscopy is used when it captures a significant fraction of the
total galaxy flux and has high signal to noise. Accurate
matched-aperture photometry from the ultraviolet to the mid-infrared
was measured with archival imaging from the GALEX, Swift UV/optical
monitor telescope (UVOT), SDSS III, Two Micron All Sky Survey, Spitzer
Space Telescope, and WISE.
