“…The overall relationship between Markarian galaxies and their local environment has been discussed by Gisler (1978) and Petrosian & Turatto (1986a, 1986b and studied in more detail for a subsample of Markarian AGNs (e.g., Petrosian 1982;Dahari 1985;MacKenty 1989MacKenty , 1990Laurikainen & Salo 1995;De Robertis et al 1998) with some controversial results. In order to address some of these issues and deal with random projection effects in a statistical manner, we systematically counted the neighboring galaxies around each Markarian galaxy to build a homogeneous data set for analysis.…”

A database for the entire Markarian catalog is presented that combines extensive new measurements of their optical parameters with a literature and database search. The measurements were made using images extracted from the STScI Digitized Sky Survey (DSS) of F pg (red) and J pg (blue) band photographic sky survey plates obtained by the Palomar and UK Schmidt telescopes. We provide accurate coordinates, morphological type, spectral and activity classes, red and blue apparent magnitudes, apparent diameters, axial ratios, and position angles, as well as number counts of neighboring objects in a circle of radius 50 kpc. Special attention was paid to the individual descriptions of the galaxies in the original Markarian lists, which clarified many cases of misidentifications of the objects, particularly among interacting systems, larger galaxies with knots of star formation, possible stars, and cases of stars projected on galaxies. The total number of individual Markarian objects in the database is now 1544. We also include redshifts that are now available for 1524 objects with UV-excess radiation, as well as galactic color excess E(B À V ) values and their 2MASS or DENIS infrared magnitudes. The database also includes extensive notes that summarize information about the membership of Markarian galaxies in different systems of galaxies and about new and revised activity classes and redshifts. An atlas of several interesting subclasses of Markarian galaxies is also presented.

“…In two samples in [16,17] and following detailed studies (e.g. [18]), the class of double and multiple nuclei Markarian galaxies was introduced. Later, large numbers of the studies have been addressed to these objects.…”

“…For example, Markarian 266, which was first studied thoroughly in [18] in 1980, currently may account more than one dozen detailed investigations in different wavelengths (e.g. [20][21][22]).…”

The catalogue of close neighbors of Markarian galaxies located inside of circles with radii 60 kpc from the centers of Markarian objects is presented, which combines extensive new measurements of their optical parameters with a literature and database search. The measurements were made using images extracted from the Digitized Sky Survey (DSS) Jpg (blue), Fpg (red) and Ipg (near-infrared) band photographic plates. We provide names, accurate coordinates, redshifts, morphological types, blue, red and near-infrared apparent magnitudes, apparent blue major diameters, axial ratios, as well as position angles for the neighbor galaxies. We also include their 2MASS infrared magnitudes. The total number of Markarian galaxies in the database is 274 and number of their neighbors is 359. The physical parameters of the systems of Markarian galaxies and their neighbors are determined and presented.Comment: 17 pages, 1 figure, 1 table, published in Astrophysics (English translation of Astrofizika
