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…
Jet MHD analytical model - framework for radiative transfer
E. E. Nokhrina, I. N. Pashchenko, V. A. Frolova +1
We developed the full magnetohydrodynamical analytical jet model that allows accurate reproducing of a transversal and longitudinal structure for a highly collimated relativistic j…
Dim cores of radio-bright AGN jets: VLBI and Gaia astrometry pinpoint different parsec-scale features
A. V. Popkov, Y. Y. Kovalev, A. V. Plavin +2
Astrometry with the very long baseline radio interferometry (VLBI) allows to determine the position of a point close to the source's brightest compact detail at milliarcsecond scal…
Looking into the Jet Cone of the Neutrino-Associated Very High Energy Blazar PKS 1424+240
Y. Y. Kovalev, A. B. Pushkarev, J. L. Gomez +7
The acceleration process of massive particles as well as the production of very high energy (VHE) photons and neutrinos remains a fundamental challenge in astrophysics. We investig…
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…
MOJAVE -- XXII. Brightness temperature distributions and geometric profiles along parsec-scale AGN jets
E. V. Kravchenko, I. N. Pashchenko, D. C. Homan +5
Radial gradients of the brightness temperatures along the parsec-scale jets of Active Galactic Nuclei (AGN) can be used to infer the energy balance and to estimate the parameter ra…
