Very Long Baseline Interferometry: Techniques and Applications

The quest for high resolution has preoccupied radio astronomers ever since radio waves were first detected from space fifty years ago. This venture was particularly stimulated by the discovery of quasars, and led to the development of interferometer techniques using baselines of transglobal dimensions. These methods have become known as Very Long Baseline Interferometry (VLBI). Arrays of radio telescopes situated all over the Earth (or even in space) are regularly used for researches in rad...
