Ultradeep ATCA Imaging of 47 Tucanae Reveals a Central Compact Radio Source

Ultradeep ATCA Imaging of 47 Tucanae Reveals a Central Compact Radio Source

We present the results of an ultradeep radio continuum survey, containing ∼480 hr of observations, of the Galactic globular cluster 47 Tucanae with the Australia Telescope Compact Array. This comprehensive coverage of the cluster allows us to reach rms noise levels of 1.19 μ Jy beam ^−1 at 5.5 GHz,...
