Starburst Driven Thermal and Non-thermal Structures in the Galactic Center Region

F. Yusef-Zadeh, W. Cotton, J. Hewitt +3

We briefly review the prominent thermal and nonthermal sources near the Galactic center. These sources include the young stellar clusters, the Sgr B complex as well as the large-sc…

Parsec Scale Properties of Radio Sources

G. Giovannini, M. Giroletti, G. B. Taylor +3

We present a new complete sample of radio sources selected from the B2 and 3CR catalogues, with no bias respect to the jet velocity and orientation. Using preliminary data we inves…

Parsec-scale properties of a complete sample of radio galaxies

T. Venturi, G. Giovannini, L. Feretti +2

We report the most important results on the parsec-scale properties of a complete sample of radio galaxies carried out at radio frequencies with the Global VLBI array and with the…

VLBI Observations of Mkn 501 and Mkn 421

G. Giovannini, L. Feretti, T. Venturi +2

We present here two epochs of Space VLBI observations at 18 cm of the BL-Lac type object Mkn 501. Thanks to the high resolution of these new data we have found that the inner jet i…
