Abstract:
The Spitzer-SDSS-GALEX Spectroscopic Survey (SSGSS) provides a new
sample of 101 star-forming galaxies at z<0.2 with unprecedented
multi-wavelength coverage. New mid- to far-infrared spectroscopy from
the Spitzer Space Telescope is added to a rich suite of previous
imaging and spectroscopy, including ROSAT, Galaxy Evolution Explorer,
Sloan Digital Sky Survey, Two Micron All Sky Survey, and
Spitzer/SWIRE. Sample selection ensures an even coverage of the full
range of normal galaxy properties, spanning two orders of magnitude in
stellar mass, color, and dust attenuation. In this paper we present
the SSGSS data set, describe the science drivers, and detail the
sample selection, observations, data reduction, and quality
assessment.
Description:
The full SSGSS sample was observed with the IRS on board the Spitzer
Space Telescope as a Cycle-3 Legacy Survey. All spectroscopic
observations were performed in spectral mapping mode. Observations
were divided between 29 Astronomical Observation Requests (AORs), each
consisting of four to eight galaxies observed in cluster mode.
