Abstract:
We present deep ATCA radio images of the globular cluster 47 Tucanae made at 1.4 and 1.7 GHz and indentify 9 compact sources in the cluster core with 11 pulsars. At present there are several pulsars for which pulse timing analyses have not yet yielded precise positions. We examine other sources in the image, and on the basis of their spectral index find two that would possibly correspond to the pulsars with undetermined positions.
Keywords: Pulsars, Globular cluster:47 Tucanae, radio continuum
