The Ursa Major supercluster of galaxies: I. The luminosity function

摘要: Catalogs of bright galaxies in the central regions 11 clusters Ursa Major supercluster are presented. Absolute and relative coordinates total B R magnitudes given for each galaxy. Plates taken with 2-m Tautenburg Observatory telescope CCD images obtained 6-m 1-m SAO telescopes used. The luminosity functions (LFs) cluster nuclei (3 Mpc×3 Mpc) composite LF constructed. is well fitted by a Schechter function \(M_B^ * = - 20\mathop .\limits^m 91\), α=−1.02 \(M_R^ 22\mathop 39\), α=−1.06. A comparison LFs field various samples superclusters shows that have parameters characteristic and, thus, differ from those Corona Borealis supercluster, which apparently at later stage dynamical evolution.
