Radio-Optical Study of Double-Peaked AGNs. I. 3C 390.3
J. Leon-Tavares, A. P. Lobanov, V. H. Chavushyan +1
We aim to test the model proposed to explain the correlation between the flux density at 15 GHz of a stationary component in the parsec-scale jet and the optical continuum emission…
Opacity in compact extragalactic radio sources and its effect on radio-optical reference frame alignment
Y. Y. Kovalev, A. P. Lobanov, A. B. Pushkarev +1
Accurate alignment of the radio and optical celestial reference frames requires detailed understanding of physical factors that may cause offsets between the positions of the same…
Compact radio jets and nuclear regions in active galaxies
Andrei Lobanov
VLBI observations of relativistic outflows (jets) in galactic nuclei, complemented with detailed studies made in other spectral domains, have become an effective tool for investiga…
How Compact are the Cores of AGN? Sub-Parsec Scale Imaging with VLBI at Millimeter Wavelengths
T. P. Krichbaum, S. S. Lee, A. P. Lobanov +2
We study the most central regions of AGN jets with an angular resolution of tens of micro-arcseconds using VLBI at millimeter wavelengths (mm-VLBI). We present and discuss a new 86…
Kelvin-Helmholtz modes revealed by the transversal structure of the jet in 0836+710
M. Perucho, A. P. Lobanov
Studying transversal structure in extragalactic jets is crucial for understanding their physics. The Japanese led space VLBI project VSOP has offered arguably the best opportunity…
Compact jets as probes for sub-parsec scale regions in AGN
Andrei Lobanov
Compact relativistic jets in active galactic nuclei offer an effective tool for investigating the physics of nuclear regions in galaxies. The emission properties, dynamics, and evo…
