Observable quality assessment of broadband very long baseline interferometry system
Ming H. Xu, James M. Anderson, Robert Heinkelmann +3
The next-generation, broadband geodetic very long baseline interferometry system, named VGOS, is developing its global network, and VGOS networks with a small size of 3--7 stations…
Evidence of the --VLBI position differences being related to radio source structure
Ming H. Xu, Susanne Lunz, James M. Anderson +3
We report the relationship between the --VLBI position differences and the magnitudes of source structure effects in VLBI observations. Because the --VLBI position diff…
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…
A LOFAR Observation of Ionospheric Scintillation from Two Simultaneous Travelling Ionospheric Disturbances
Richard A. Fallows, Biagio Forte, Ivan Astin +55
This paper presents the results from one of the first observations of ionospheric scintillation taken using the Low-Frequency Array (LOFAR). The observation was of the strong natur…
Multiband RadioAstron space VLBI imaging of the jet in quasar S5 0836+710
L. Vega-García, A. P. Lobanov, M. Perucho +11
Detailed studies of relativistic jets in active galactic nuclei (AGN) require high-fidelity imaging at the highest possible resolution. This can be achieved using very long baselin…
A wide and collimated radio jet in 3C 84 on the scale of a few hundred gravitational radii
G. Giovannini, T. Savolainen, M. Orienti +22
Understanding the launching, acceleration, and collimation of jets powered by active galactic nuclei remains an outstanding problem in relativistic astrophysics. This is partly bec…
