Comparison of clustering properties of observed objects and dark matter halos on different mass and spatial scales
A. V. Tikhonov, A. I. Kopylov, S. Gottlober +1
We investigate the large-scale distribution of galaxy clusters taken from several X-ray catalogs. Different statistics of clustering like the conditional correlation function (CCF)…
VV124 (UGC4879): A new transitional dwarf galaxy in the periphery of the Local Group
Alexander I. Kopylov, Nikolay A. Tikhonov, Sergey Fabrika +2
We present the first resolved-star photometry of VV124 (UGC4879) and find that this is the most isolated dwarf galaxy in the periphery of the Local Group. Based on imaging and spec…
Peculiar Motions in the Region of the Ursa Major Supercluster of Galaxies
Flera G. Kopylova, Alexander I. Kopylov
We have investigated the peculiar motions of clusters of galaxies in the Ursa Major (UMa) supercluster and its neighborhood. Based on SDSS (Sloan Digital Sky Survey) data, we have…
On the Photometric Redshift Estimates for FR II Radio Galaxies
O. V. Verkhodanov, A. I. Kopylov, Yu. N. Pariiskii +2
Using the photometric data on FR II radio galaxies obtained in the Big Trio Program and data from other sources, we confirmed the stable correlation between the spectroscopic and p…
RC J0311+0507: A Candidate for Superpowerful Radio Galaxies in the Early Universe at Redshift z=4.514
A. I. Kopylov, W. M. Goss, Yu. N. Pariiskii +4
A strong emission line at 6703A has been detected in the optical spectrum for the host galaxy (R=23.1) of the radio source RC J0311+0507 (4C+04.11). This radio galaxy, with a spect…
Photometric study of radio galaxies in RATAN--600 "Cold" survey
O. V. Verkhodanov, Yu. N. Parijskij, N. S. Soboleva +4
About 100 steep spectrum radio sources from the RATAN--600 RC catalog were mapped by the VLA and identified with optical objects down to 24--25 in the R band using the 6 m…
