Variable Radio Source Structure on a Scale of Several Minutes of Arc (1),

Abstract

During the course of high frequency flux density measurements on sources exhibiting low frequency cutoffs, at least three such sources 4C 79.4, 4C 79.15, 9and PKS 2344+09, revealed structure on a scale ranging from a fraction of a minute of arc to as much as fifteen minutes of arc. This structure appears to change significantly on a time scale of several months. It is suggested that this variable structure arises from the existence of several centers that are highly variable in flux density, but fixed in position.
