Observations with a VLB Array. The Sources 3C120, 3C273, 2134+004, and 3C84. III.

Abstract

The sources 3C120, 3C273, 2134+004 and 3C84 were observed at several apochs at 2.8 cm using a multi-element very-long-baseline interferometer. The resulting visibility data show that the brightness distributions of each source are variable. There are large changes in the visibilities of 3C120 and 3C273 on a time scale of months. For 3C120, and perhaps 3C273, the changes can be explained by source distributions in which the components are separating at high (probably relativistic) speeds.
