Description

A radio survey of X-ray emitting globular clusters has been conducted at 327 MHz and the results are presented. Fourteen radio sources are detected within the total area encompassed by one tidal radius of the clusters. Statistically, there is no excess of radio sources in these fields, but two sources are found which may be associated with the globular clusters NGC 5272 and NGC 6656. Significant differences in positional coincidence, radio flux density, and size of the radio sources are found with some of the earlier radio observation of similar nature. The nature of a double-lobed radio structure detected for the X-ray source 1E 1339.9+28 is discussed. 28 refs
