Radio sources near the core of globular cluster 47 Tucanae


We present ATCA radio images of the globular cluster 47 Tucanae made at 1.4 and 1.7 GHz and provide an analysis of the radio sources detected within 5 of the cluster centre. 11 sources are detected, most of which are clustered about the core of 47 Tuc. Both of the pulsars in 47 Tuc whose positions are known can be identified with sources in the 1.4 GHz image. The source distribution has a characteristic radius of ∼100, larger than the 23 radius of the cluster core. We compare source positions with the positions of nine X-ray sources and find no correspondence.
