“…In two recent papers, Arakelian, Dibai, and Esipov (1975) and Doroshenko and Terebizh (1975) have presented spectral observations of a total of 90 emissionline objects from a list of high-surface-brightness galaxies (Arakelian 1975). Seven of these emission-line galaxies were described as possible Seyfert galaxies, based on low-resolution image-tube spectra of the visible and red spectral regions, and we therefore obtained spectral scans of these objects as part of our survey of Seyfert galaxies.…”

Descriptions of the emission-line spectra of seven Arakelian galaxies are given. Two of the galaxies have very lowexcitation, weak emission lines, and are definitely not Seyfert galaxies. Two have emission-line spectra which are similar to M51 and M81, and a third is closer to these objects than to Seyfert 2's. One galaxy, Akn 79, is a typical Seyfert 2 object, while another, Akn 120, has the spectrum of a typical Seyfert 1. Relative emission-line intensities are given for Akn 120, and the line profiles of Hß and Ha are shown to differ significantly in form and width. The equivalent width of Hß in Akn 120 is very large (190 Á), and is difficult to account for by photoionization alone.

“…Markarian galaxies have been studied by various observational methods, such as morphologically (e.g. Korovyakovskii et al 1981), spectroscopically (Arakelyan et al 1973, Weedman & Khachikyan 1968 and references therein), as well as in different wavelength ranges (see below). Petrosian et al (1989) have studied double and multiple structure of some Markarian galaxies.…”

Markarian survey (or the First Byurakan Survey, FBS) was the first systematic survey for active galaxies and was a new method for search for such objects. Until now, it is the largest objective prism survey of the sky (17,000 deg2). It was carried out in 1965-1980 by B. E. Markarian and his colleagues and resulted in discovery of 1517 UV-excess (Markarian) galaxies. They contain many active galaxies, as well as powerful gamma-, X-ray, IR and radio sources (Mrk 180, 231, 421, 501, etc.), BCDGs (Mrk 116) and interacting/merging systems (Mrk 266, 273, etc.). They led to the classification of Seyfert galaxies into Sy1 and Sy2 and the definition of Starbursts (SB). Several catalogs of Markarian galaxies have been published (Bicay et al., 1995, Markarian et al., 1989, Mazzarella & Balzano, 1986, Petrosian et al., 2007) and they are accessible in all corresponding databases. Markarian survey also served as a basis for search for UVX stellar objects (including QSOs and Seyferts), late-type stars and optical identification of IR sources. At present the survey is digitized and DFBS database is available. We review the main characteristics of the Markarian survey, its comparison with other similar surveys and the importance of Markarian galaxies in modern astrophysics.
