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-…
Gravitational lens surveys with LOFAR
Olaf Wucknitz, Mike Garrett
Deep surveys planned as a Key Science Project of LOFAR provide completely new opportunities for gravitational lens searches. For the first time do large-scale surveys reach the res…
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…
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…
HI imaging of Galaxy Clusters at z=0.2; a Pilot Survey of Abell 963 and Abell 2192
Marc Verheijen, Jacqueline van Gorkom, Arpad Szomoru +3
A pilot study with the powerful new backend of the Westerbork Synthesis Radio Telescope (WSRT) of two galaxy clusters at z=0.2 has revealed neutral hydrogen emission from 39 galaxi…
High-resolution radio imaging of the most distant radio quasar SDSS J0836+0054
S. Frey, Z. Paragi, L. Mosoni +1
We observed SDSS J0836+0054, the most distant radio-loud quasar known at present (z=5.774) with the European Very Long Baseline Interferometry (VLBI) Network at the 5 GHz frequency…
