1996A&A...305...33K The Local Group in comparison with other nearby groups of galaxies Igor Karachentsev Special Astrophysical Observatory, Russian Academy of Sciences, N.Arkhyz, Zelenchukskaja, Stavropolsky kraj, 357147, Russia e-mail: ikar@sao.stavropol.su Received 10 October 1994/Accepted 19 May 1995 Abstract. Ensembles of probable physical companions around nearby massive galaxies with V_0_ < 500 km s^-1^ and M > 3 x 10^11^ M_sun_ are derived. Recent estimates of distances for galaxies, a new criterion of membership, and also special searches for diffuse ("spheroidal") dwarf objects have been used for this purpose. Under such an approach the Milky Way has thirteen companions, M31 eleven, M81 fifteen, NGC 5128 ten, NGC 5236 five, and M 101 has seven. According to linear dimension (140 kpc), radial velocity dispersion (68 km s^-1^), and morphological content (62 percent of E+Sph) the Local Group appears a common one among other systems. Some properties of structure and kinematics of the nearby groups are noted in relation to the luminosity ratio of their two brightest members. The dynamical status of the 6 nearby groups can be explained also without invoking significant amounts of Dark Matter beyond 2-3 standard radii of the principal galaxies. Key words: galaxies: Local Group - galaxies: clusters of- dark matter
