Objective prism survey for emission-line galaxies (IV).
Abstract
The results of an objective prism survey of emission-line galaxies using the Beijing Observatory 60-cm Schmidt are given. The survey includes 100 emission-line objects, of which 96 are emission-line galaxies, 3 are planetary nebulae and 1 is an emission-line star. Of the emission-line galaxies, 69-72 percent are of types s or sd; 27-28 percent are of types d and ds. In addition to 4 known Seyfert galaxies, there are at least 5 probable Seyferts. Twenty-three of the objects are IRAS sources characterized by strong emission phenomena.
