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-…

High-resolution double morphology of the most distant known radio quasar at z=6.12

S. Frey, L. I. Gurvits, Z. Paragi +1

Context: The highest redshift quasars at z>~6 receive considerable attention since they provide strong constraints on the growth of the earliest supermassive black holes. They also…

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…

Potential Targets for ASTRO-G In-Beam Phase-Referencing

S. Frey, K. E. Gabanyi

We show that as many as ~50 quasars with at least mJy-level expected flux density can be pre-selected as potential in-beam phase-reference targets for ASTRO-G. Most of them have ne…

Deep Extragalactic VLBI-Optical Survey (DEVOS) II. Efficient VLBI detection of SDSS quasars

S. Frey, L. I. Gurvits, Z. Paragi +3

Context: The Deep Extragalactic VLBI-Optical Survey (DEVOS) aims at constructing a large sample of compact radio sources up to two orders of magnitude fainter than those studied in…

The VSOP Survey: Final individual results + Final aggregate results

R. Dodson, S. Horiuchi, W. Scott +10

In February 1997 the Japanese radio astronomy satellite HALCA was launched to provide the space-borne element for the VSOP mission. HALCA provided linear baselines three-times grea…
