Spectroscopy of Zwicky galaxies identified with B3 radiosources
Results are presented of long-slit CCD spectroscopy of 33 Zwickygalaxies identified in the B3 Survey as radiosources, includinginformation on morphological classification, photographic magnitude,line identification, measured wavelength, adopted rest wavelength,redshift computed for the line, and average redshift and rms. In thissample, 24 galaxies showed emission (and often absorption) lines, while9 galaxies showed only absorption lines. Nine of the 14 galaxiesclassified as E/SO showed the forbidden N II emission line at an EW(lim)= 1.5 A. The rest were classified as Spirals, and, out of 19 of thesegalaxies, 15 showed the forbidden N II emission line. No significantdifferences were found between the percentage of galaxies with emissionlines in this sample and the samples of optically selected galaxies ofsimilar equivalent width limit.
