    The Adopted Morphological Types of 247 Rich PF Galaxy Clusters
    (2016) Panko, Olena O.; Bajan, Katarzyna; Flin, Piotr; Gotsulyak, Alla; Панько, Олена Олексіївна; Панько, Елена Алексеевна
    Morphological types were determined for 247 rich galaxy clusters from the PF Catalogue of Galaxy Clusters and Groups. The adopted types are based on classical morphological schemes and consider concentration to the cluster center, the signs of preferential direction or plane in the cluster, and the positions of the brightest galaxies. It is shown that both concentration and preferential plane are significant and independent morphological criteria.

    The Investigation of the Luminosity Function for Sample 6168 Galaxy Clusters
    (2018) Godlowski, Wlodzimierz; Popiela, Joanna; Biernacka, Monika; Bajan, Katarzyna; Panko, Olena O.; Pajowska, Paulina; Flin, Piotr; Панько, Олена Олексіївна; Панько, Елена Алексеевна
    The issue of construction of the luminosity function is an important problem for analysis of large scale structure statistics and interpretation of astronomical object counts In the present paper we discuss the the issure of the construction of the luminosity function for galaxy clusters. The problem is solved based on counting brightness of galaxies belonging to 6168 galaxy clusters selected from Panko & Flin (2006) Catalogue. We show that the galaxy clusters are characterized by the luminosity function signi cantly di erent than that obtained for both: individual optical galaxies and radiogalaxies. We discuss the signi cance of this result for the theories of the structure formation.
