Here we present very long baseline interferometry observations of the Galactic radio and X-ray source GRO J1655-40. These observations show that the radio source which appeared approximately two weeks after the initial X-ray outburst consisted of two prominent components which separated with an apparent speed of 1.5±0.4c. When the various possibilities for the geometry of the radio source are taken...
We present dual-frequency, co-eval very long baseline interferometry observations of the sub-parsec-scale radio source in Centaurus A which identify the core of the radio source, the origin of the parsec-scale and kiloparsec-scale radio emission. In addition we present multi-epoch observations at a frequency of 8.4 GHz which show the complex evolution of the sub-parsec-scale morphology over a 3.3...
The international radio-astronomy community is proposing to build a telescope of unprecedented size in order to allow observation of the farthest reaches of space. This telescope is known as the Square Kilometre Array (SKA), and will be built in one of two southern-hemisphere candidate locations; with the core located in either the West Australian desert, or the Northern Cape region of South Africa...
