Object S5 0716+71: Flux - linear polarization coupling
V. R. Amirkhanyan
The linear polarization observations of S5 0716+71 carried out by the author in 2019-2021 were continued from December 8, 2021 to March 12, 2022. These observations confirm the aut…
Small telescopes being effective: MAGIC or not?
Victor L. Afanasiev, Eugene A. Malygin, Elena S. Shablovinskaya +4
The paper describes the MAGIC multi-mode focal reducer (Monitoring of Active Galaxies by Investigation of their Cores), commissioned on the 1-m Zeiss-1000 telescope of the Special…
SCORPIO-2 Guiding and Calibration System in the Prime Focus of the 6-m Telescope
Victor L. Afanasiev, Vladimir R. Amirkhanyan, Alexei V. Moiseev +2
We describe a device (adapter) for off-axis guiding and photometric calibration of wide-angle spectrographs operating in the prime focus of the 6-m telescope of the Special Astroph…
Radiation Pattern of Radio and Optical Components of Extended Radio Sources
V. R. Amirkhanyan
The relation between parameters the D/sqrt(I) and Ic/Isum and radiation patterns of the optical and radio components of an extended radio source is analyzed, where D and I are the…
Technique of Polarimetric Observations of Faint Objects at the 6-m BTA Telescope
V. L. Afanasiev, V. R. Amirkhanyan
We describe the technique of spectropolarimetric observations allowing for the measurements of the Stokes parameters in one of the observational modes of the SCORPIO focal reducer…
New Extended Radio Sources From the NVSS
V. R. Amirkhanyan, V. L. Afanasiev, A. V. Moiseev
We report the results of the spectroscopic observations carried out at the SAO RAS 6-m telescope for the optical components of nine new extended radio sources found in the NVSS cat…
Angular Size-Redshift: Experiment and Calculation
V. R. Amirkhanyan
In this paper the next attempt is made to clarify the nature of the Euclidean behavior of the boundary in the angular size-redshift cosmological test. It is shown experimentally th…
Anisotropy of the space orientation of radio sources. II: The axis distribution function
V. R. Amirkhanyan
An analysis of the position angles distribution of 10461 extended radio sources shows that the spatial orientation of the axes of these objects is anisotropic: they avoid the direc…
Anisotropy of the space orientation of radio sources. I: The catalog
V. R. Amirkhanyan
A catalog of the extended extragalactic radio sources consisting of 10461 objects is compiled based on the list of radio sources of the FIRST survey. A total of 1801 objects are id…
