Scientific paper
The state of VLBI observations of active nuclei is reviewed and the expcted impact of QUASAT is discussed. The most powerful extragalactic objects, radio souces are divided into three main classes according to morphology and spectral index, viz. extended steep spectrum objects, in which the central galaxy is straddled by two large lobes of emission; compact steep spctrum objects; and compact flat spectrum objects. It is shown that three are very compact, unresolved features in the central core of all three classes. Observations with QUASAT could probe objects on interesting physical scales down to 10 to the 17th power cm. In particular QUASAT will be ideal or studying superluminal sources, and other variable objects, and it may enable detailed study of the formation and propagation of relativistic shocks in active nuclei.
