The Apparent "Angular Size - Frequency" Dependence in ~3000 Parsec-scale Extragalactic Jets
J. Yang, L. I. Gurvits, S. Frey +1
The upper envelope of the amplitude of the VLBI visibility function usually represents the most compact structural pattern of extragalactic radio sources, in particular, the "core-…
Array configuration studies for the SKA -- Implementation of figures of merit based on SDR
Dharam V. Lal, Andrei P. Lobanov
The Square Kilometre Array is going to become operational at the time when several new large optical, X-ray and Gamma-ray telescopes are expected to be working. The main drive for…
Physical information derived from the internal structure in jets
M. Perucho, A. P. Lobanov, Y. Y. Kovalev
We present the first results on the analysis of the structures observed in the jet of the quasar 0836+710. We obtain the ridge lines of the jet at different epochs and several freq…
Opacity in compact extragalactic radio sources and its effect on astrophysical and astrometric studies
Y. Y. Kovalev, A. P. Lobanov, A. B. Pushkarev +1
The apparent position of the "core" in a parsec-scale radio jet (a compact, bright emitting region at the narrow end of the jet) depends on the observing frequency, owing to synchr…
High-Redshift Quasars at the Highest Resolution: VSOP Results
S. Frey, L. I. Gurvits, A. P. Lobanov +2
We studied the radio structure of high-redshift (z>3) quasars with VSOP at 1.6 and 5 GHz. These sources are the most distant objects ever observed with Space VLBI, at rest-frame fr…
