1991ApJS...75..297H AN OPTICAL CATALOG OF EXTRAGALACTIC EMISSION-LINE OBJECTS SIMILAR TO QUASI-STELLAR OBJECTS A. HEWITT AND G. BURBIDGE Center for Astrophysics and Space Sciences, University of California, San Diego Received 1990 April 17; accepted 1990 June 11 ABSTRACT A catalog of 935 galaxies which have optical properties similar to those of QSOs is given. A subsidiary table of cross-identifications enables the reader to relate the name of a given object to its coordinate name. Most of the objects appear to be nonstellar. The majority, more than 700, have redshifts z <= 0.2, and have mostly been classified as Seyfert galaxies, N systems, or radio galaxies. The Hubble diagram for all of the objects with z <= 0.2 is shown. The redshift distribution peaks at z ~0.025, but there are about 200 powerful radio galaxies in the extended tail of the distribution which have z > 0.2. There is a separate and distinct peak in the redshift distribution at z = 0.06. Subject headings: galaxies: redshifts - galaxies: Seyfert - quasars
