The 18CM Visibility Functions of High Frequency Compact Sources, (11),

Abstract

Observations at 18 cm, with an angular resolution of approximately 0.01 sec., of the strongest compact radio sources with milliarcsecond structure at shorter wavelengths (6-2 cm) show that most of the sources are only slightly resolved, and most of the 18 cm radiation comes from quite small components, probably the same components seen at the short wavelengths. Some sources have brightness temperatures > 10 to the 12th power K. Weak emissions were detected from the nucleus of Centaurus A. The May, 1974 radio outburst of Cyg X-3 appears to have had an expansion velocity of about 0.2 c.
