Heavy interstellar scattering toward the near end of the Galactic bar
A. B. Pushkarev, A. Brunthaler, Y. Y. Kovalev +8
We present results of a pilot observational wide-field VLBI campaign on probing scattering properties of the partly ionized interstellar medium towards the Galactic plane sky regio…
Probing plasma scattering screens towards the quasar 2005+403 with long-term RATAN-600 observations
T. A. Koryukova, S. A. Trushkin, I. N. Pashchenko +1
We continue investigating the observed properties of the quasar 2005403 seen through the highly turbulent plasma in the Cygnus region. Our earlier study Koryukova+2023 revealed…
Depolarization and Faraday effects in AGN Jets
E. Yushkov, I. N. Pashchenko, D. D. Sokoloff +1
Radio interferometric observations of Active Galactic Nuclei (AGN) jets reveal the significant linear polarization of their synchrotron radiation that changes with frequency due to…
A bias in VLBI measurements of the core shift effect in AGN jets
I. N. Pashchenko, A. V. Plavin, A. M. Kutkin +1
The Blandford and Königl model of AGN jets predicts that the position of the apparent opaque jet base - the core - changes with frequency. This effect is observed with radio interf…
Detection statistics of the RadioAstron AGN survey
Y. Y. Kovalev, N. S. Kardashev, K. V. Sokolovsky +57
The largest Key Science Program of the RadioAstron space VLBI mission is a survey of active galactic nuclei (AGN). The main goal of the survey is to measure and study the brightnes…
Inferring AGN jet parameters using Bayesian analysis of VLBI data with non-uniform jet model
Ilya N. Pashchenko, Alexander V. Plavin
Physical parameters of AGN jets observed with Very Long Baseline Interferometry (VLBI) are usually inferred from the core shift measurements or flux and size measured at a peak fre…
