Studies of stationary features in jets: 3C 279 quasar I. On-sky scattering and dynamics
T. G. Arshakian, L. A. Hambardzumyan, A. B. Pushkarev +2
A recent study on the dynamics of the quasi-stationary component (QSC) in the jet of BL~ Lacertae highlighted its significance in evaluating the physical properties of relativistic…
Studies of stationary features in jets: BL Lacertae II. Trajectory reversals and superluminal speeds on sub-parsec scales
T. G. Arshakian, L. A. Hambardzumyan, A. B. Pushkarev +1
High-resolution VLBI observations revealed a quasi-stationary component (QSC) in the relativistic jets of many blazars, which represents a standing recollimation shock. The VLBA mo…
Baldwin Effect and Additional BLR Component in AGN with Superluminal Jets
V. M. Patiño-Ávarez, J. Torrealba, V. Chavushyan +4
We study the Baldwin Effect (BE) in 96 core-jet blazars with optical and ultraviolet spectroscopic data from a radio-loud AGN sample obtained from the MOJAVE 2 cm survey. A statist…
The relation between magnetic and material arms in models for spiral galaxies
D. Moss, R. Beck, D. Sokoloff +3
Context. Observations of polarized radio emission show that large-scale (regular) magnetic fields in spiral galaxies are not axisymmetric, but generally stronger in interarm region…
Multiscale magnetic fields in spiral galaxies: evolution and reversals
David Moss, Rodion Stepanov, Tigran Arshakian +3
Magnetic fields in nearby, star-forming galaxies reveal both large-scale patterns and small-scale structures. A large-scale field reversal may exist in the Milky Way but no such re…
