Redshifts measured for 16 previously unstudied Markarian galaxies are presented. The galaxies, from the eighth and ninth Markarian lists, were observed with an image dissector scanner on the 1.8-m Perkins telescope at the Lowell Observatory at low and moderate resolution between wavelengths of 4500 and 7200 A. Of the 16 galaxies observed, no emission features or reliable absorption features were detected in the spectra of Mrk 713, Mrk 760 or Mrk 866, and Mrk 712 and Mrk 800 showed spectral features suggestive of high-excitation emission-line galaxies. Two pairs of galaxies, Mrk 775/Mrk 776 and Mrk 827/Mrk 828, were observed which had redshifts so close as to suggest a physical association, and estimates of the minimum mass of these systems were obtained. |
