Toggle Full Description

This is the Beta version of "An Atlas of Galaxy Spectral Energy Distributions From The UV to the Mid-Infrared" and will be updated once the paper is accepted for publication. The first folder contains all the SEDs, while the folders for individual galaxies contain the SEDs and images used to constrain and verify the SEDs. We present an atlas of 129 spectral energy distributions for nearby galaxies, with wavelength coverage spanning from the UV 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 MAGPHYS models. The spectroscopy and models were normalized, constrained and verified using matched aperture photometry measured using imaging from Swift, GALEX, SDSS, 2MASS, Spitzer and WISE. 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.
