High Frequency Peak Radio Sources from the AT20G Catalogue and Their Radio Spectra

Elena Majorova, Olga Zhelenkova

A sample of high-frequency peaker (HFP) candidates was formed from the AT20G catalog radio sources with spectral indices of the optically thick emission region exceedin…

New Radio Data on Sources of the Big Trio Program for Searching for Distant Radio Galaxies

Olga Zhelenkova, Adelina Temirova, Yurij Parijskij +1

Radio sources with steep and ultra-steep spectra, identified through a series of surveys of the Cold experiment using the RATAN-600 radio telescope, formed the basis of the Big Tri…

A sample of giant radio sources from the NVGRC catalog

Olga Zhelenkova, Milena Khoruzhenko

We present the results of a search for megaparsec-scale sources in the NVGRC catalog of candidates of giant radio source (GRS) based on the NVSS sky survey. We visually inspected 3…

Study of RCR Catalogue Radio Source Integral Spectra

Olga Zhelenkova, Elena Majorova

We present the characteristics of the sources found on the averaged scans of the "Cold" experiment 1980--1999 surveys in the right-ascension interval < RA <. Thereby, a r…

The Excess Density of Field Galaxies near z=0.56 around the Gamma-Ray Burst GRB021004 Position

I. V. Sokolov, A. J. Castro-Tirado, O. P. Zhelenkova +3

We test for reliability any signatures of field galaxies clustering in the GRB 021004 line of sight. The first signature is the GRB 021004 field photometric redshifts distribution…

Search for Variable Sources Using Data of "Cold" Surveys

E. K. Majorova, O. P. Zelenkova

We search for variable sources, using the data of the surveys conducted on the RATAN-600 radio telescope in 1980-1994 at 3.94 GHz. To test the radio sources of the RCR (RATAN Cold…
