The parkes half-jansky flat-spectrum sample
We present a new sample of Parkes half-jansky flat-spectrum radio sources, having made a particular effort to find any previously unidentified sources. The sample contains 323 sources selectedExpand

The Subparsec-Scale Structure and Evolution of Centaurus A: The Nearest Active Radio Galaxy
?????The subparsec-scale structure of Cen A is complex, consisting of a bright jet and a fainter counterjet. The bright jet contains components that have subluminal speeds of approximately 0.1c andExpand

The Time Delay in the Gravitational Lens PKS 1830–211
We have measured a time delay of 26+ 4−5 days and a magnification ratio of 1.52±0.05 in the strong radio gravitational lens PKS 1830-211. Observations were made over the 18 month period from 1997Expand

Astrometric Detection of a Low Mass Companion Orbiting the Star AB Doradus
We report submilliarcsecond-precise astrometric measurements for the late-type star AB Doradus via a combination of VLBI (very long baseline interferometry) and HIPPARCOS data. Our astrometricExpand

The Nearest GHz Peaked-Spectrum Radio Galaxy, PKS 1718-649
In this paper we identify PKS 1718-649, at a distance of 56 Mpc (z=0.014; H0=75 km s-1 Mpc-1, q0=O), as the nearest GHz peaked-spectrum (GPS) radio galaxy, more than four times closer than anyExpand
