Linear polarization in the nucleus of M87 at 7 mm and 1.3 cm
E. V. Kravchenko, M. Giroletti, K. Hada +4
We report on high angular resolution polarimetric observations of the nearby radio galaxy M87 using the Very Long Baseline Array at 24 GHz (1.3 cm) and 43 GHz (7 mm) in 201…
Probing the innermost regions of AGN jets and their magnetic fields with RadioAstron. III. Blazar S5 0716+71 at microarcsecond resolution
Evgeniya V. Kravchenko, Jose L. Gómez, Yuri Y. Kovalev +10
We present RadioAstron Space VLBI imaging observations of the BL Lac object S5 0716+71 made on January 3-4 2015 at a frequency of 22 GHz (wavelength cm). The observations w…
Investigating the connection between gamma-ray activity and relativistic jet in 3C273 during 2015-2019
Dae-Won Kim, Sascha Trippe, Evgeniya V. Kravchenko
Due to its powerful radiation over the entire electromagnetic spectrum and its radio jet activity, the blazar 3C273 offers the opportunity to study the physics of -ray emission…
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…
The jet of S5 0716+71 at as scales with RadioAstron
E. V. Kravchenko, J. L. Gómez, Y. Y. Kovalev +1
Ground-space interferometer RadioAstron provides unique opportunity to probe detail structure of the distant active galactic nuclei at as scales. Here we report on RadioAstron o…
Multi-Frequency VLBA Polarimetry and the Twin-Jet Quasar 0850+581
E. V. Kravchenko, Y. Y. Kovalev
We present the first multi-frequency VLBA study of the quasar 0850+581 which appears to have a two-sided relativistic jet.Apparent velocity in the approaching jet changes from 3.4c…
