IVS Products for Precise Global Reference Frames
W. Schluter, N. Vandenberg
VLBI plays a unique and fundamental role in the maintenance of global reference frames which are required for precise positioning in many research areas related e.g to the understa…
Probing the polarization characteristics of SS433 on mas scales
Z. Paragi, R. C. Vermeulen, D. C. Homan +5
We present a status report of dedicated circular polarization (CP) global VLBI observations of SS433. The total intensity image of the source is presented. We do not detect linear…
The simultaneous VLA observations of Sgr A* from 90 to 0.7 cm
T. An, J. -H. Zhao, X. -Y. Hong +4
We present a spectrum of Sgr A* observed simultaneously on June 17, 2003 at wavelengths from 90 to 0.7 cm with the VLA. In the spectrum, we also include the measurements of Sgr A*…
The asymmetric compact jet of GRS 1915+105
M. Ribo, V. Dhawan, I. F. Mirabel
We present multiepoch VLBA observations of the compact jet of GRS 1915+105 conducted at 15.0 and 8.4 GHz during a {\it plateau} state of the source in 2003 March-April. These obser…
Compact Structure in FIRST Survey Sources
R. W. Porcas, W. Alef, T. Ghosh +2
We present preliminary results from a statistical survey of compact structure in faint radio sources. Around 1000 sources from the VLA FIRST survey (flux densities larger than 1 mJ…
The two sided parsec scale structure of the Low Luminosity Active Galactic Nucleus in NGC 4278
G. Giovannini, M. Giroletti, G. B. Taylor
We present new Very Long Baseline Interferometry observations of the LINER galaxy NGC 4278 with a linear resolution of < 0.1 pc. Our radio data reveal a two sided structure, with s…
