J/ApJ/559/606       Star formation in spectroscopic survey   (Carter+, 2001)

Star formation in a complete spectroscopic survey of galaxies. Carter B.J., Fabricant D.G., Geller M.J., Kurtz M.J., McLean B. <Astrophys. J. 559, 606 (2001)> =2001ApJ...559..606C
ADC_Keywords: Galaxy catalogs ; Redshifts Keywords: galaxies: active - galaxies: distances and redshifts - galaxies: fundamental parameters - galaxies: interactions - galaxies: starburst Abstract: The 15R-North galaxy redshift survey is a uniform spectroscopic survey (S/N∼10) covering the range 3650-7400Å for 3149 galaxies with median redshift 0.05. The sample is 90% complete to R=15.4. The median slit covering fraction is 24% of the galaxy, apparently sufficient to minimize the effects of aperture bias on the EW(Hα). Forty-nine percent of the galaxies in the survey have one or more emission lines detected at ≥2σ. In agreement with previous surveys, the fraction of absorption-line galaxies increases steeply with galaxy luminosity. We use Hβ, [O III], Hα, and [N II] to discriminate between star-forming galaxies and AGNs. At least 20% of the galaxies are star-forming, at least 17% have AGN-like emission, and 12% have unclassifiable emission. The data for the entire survey will appear in Geller et al. 2002, in preparation. File Summary:
