Multi-wavelength differential astrometry of the S5 polar cap sample
J. C. Guirado, J. M. Marcaide, E. Ros +2
We report on the status of our S5 polar cap astrometry program. Since 1997 we have observed all the 13 radio sources of the complete S5 polar cap sample at the wavelengths of 3.6 c…
Absolute kinematics of radio source components in the complete S5 polar cap sample
M. A. Perez-Torres, J. M. Marcaide, J. C. Guirado +1
We observed the thirteen extragalactic radio sources of the complete S5 polar cap sample at 15.4 GHz with the Very Long Baseline Array, on 27 July 1999 (1999.57) and 15 June 2000 (…
High-resolution radio imaging of young supernovae
M. A. Perez-Torres, J. M. Marcaide, A. Alberdi +12
The high resolution obtained through the use of VLBI gives an unique opportunity to directly observe the interaction of an expanding radio supernova with its surrounding medium. We…
Searching for low mass objects around nearby dMe radio stars
J. C. Guirado, E. Ros, D. L. Jones +3
Nearby M-dwarfs are best suited for searches of low mass companions. VLBI phase-referencing observations with sensitive telescopes are able to detect radio star flux-densities of t…
How is really decelerating the expansion of SN1993J?
J. M. Marcaide, A. Alberdi, M. A. Perez-Torres +14
SN1993J is to date the radio supernova whose evolution has been monitored in greatest detail and the one which holds best promise for a comprehensive theoretical-observational anal…
On the way to global phase-delay astrometry
E. Ros, J. M. Marcaide, J. C. Guirado +1
The use of the phase-delay improves substantially the accuracy obtained in VLBI astrometry with respect to the group-delay observable. Recently, Ros et al. (1999) have extended the…
