The Spitzer SDSS Galaxy Spectroscopic Survey (SSGSS) is a Cycle-3 Spitzer program to acquire 5 to 40 micron mid-infrared spectroscopy of a representative sample of galaxies from SDSS, selected for having full prior photometric coverage from the UV to the far-IR.

The full SSGSS sample includes 101 star forming galaxies from the SWIRE/Lockman Hole region. These galaxies were selected from those with full SDSS, GALEX and IRAC (4 channel) and MIPS (24 and 70 micron) photometry, with a 5.8 micron surface brightness limit of 0.75 MJy/sr and a 24 micron flux limit of 1.5 mJy.

These data represent the first public data release of the full SSGSS sample. The dataset includes short-low and long-low IRS spectroscopy for the full sample, and short-high IRS spectroscopy for a subsample of the 33 brightest galaxies.

The 101 SSGSS objects are represented as overlays in red on the SSGSS 3-color image above. Use the form below to enter a coordinate or object name to search for data, or click on any red region to get a close-up of the area; or click on the any of the SSGSS object names for a summary page of each object. Summary pages are created by IRSA to aid with data layout and visualization; these pages contain previews and links to all files provided by SSGSS for that object.
