Radio data from four extragalactic sources, three quasars and one galaxy, show evidence for an apparent expansion faster than the speed of light. The data on these ‘superluminal’ sources are reviewed, and their implications briefly discussed.

The bright radio nucleus 3C84 of the peculiar galaxy NGC1275 was among the first sources studied by VLBI techniques sixteen years ago (Clark et al., 1968). Early observations at short centimeter wavelengths using arrays of up to four telescopes (Schi

Publikováno v: Nature. 290:318-320

The discovery1 of radio structure on a scale of 10–50 m arc s in SS433 has prompted us to monitor the object with the European VLBI network. The first observations in this programme were made for periods of 9 and 10 h at a wavelength of 6 cm on 9 J
