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

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…
First e-VLBI observations of Cygnus X-3
V. Tudose, R. P. Fender, M. A. Garrett +6
We report the results of the first two 5 GHz e-VLBI observations of the X-ray binary Cygnus X-3 using the European VLBI Network. Two successful observing sessions were held, on 200…
First e-VLBI observations of GRS 1915+105
A. Rushton, R. E. Spencer, M. Strong +10
We present results from the first successful open call e-VLBI science run, observing the X-ray binary GRS 1915+105. e-VLBI science allows the rapid production of VLBI radio maps, w…
Structure in the radio counterpart to the 2004 Dec 27 giant flare from SGR 1806-20
R. P. Fender, T. W. B. Muxlow, M. A. Garrett +7
On Dec 27, 2004, the magnetar SGR 1806-20 underwent an enormous outburst resulting in the formation of an expanding, moving, and fading radio source. We report observations of this…
e-VLBI observations of SN2001em - an off-axis GRB candidate
Z. Paragi, M. A. Garrett, B. Paczynski +5
Studying transient phenomena with the Very Long Baseline Interferometry (VLBI) technique faces severe difficulties because the turnaround time of the experiments from the observati…
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…
From truck to optical fibre: the coming-of-age of eVLBI
A. Szomoru, A. Biggs, M. A. Garrett +6
Spurred by the advent of disk-based recording systems and the nearly explosive increase of internet bandwidth, eVLBI (Parsley et al. 2004) has undergone a remarkable development ov…
