Miller-Jones, James C. A., Strader, Jay, Heinke, Craig O., Maccarone, Thomas J., van den Berg, Maureen, Knigge, C., Chomiuk, Laura, Noyola, Eva, Russell, Thomas D., Seth, Anil C., Sivakoff, Gregory Robert
We report the detection of steady radio emission from the known X-ray source X9 in the globular cluster 47 Tuc. With a double-peaked C IV emission line in its ultraviolet spectrum providing a clear signature of accretion, this source had been previously classified as a cataclysmic variable. In...

47 Tuc X9 is a low-mass X-ray binary (LMXB) in the globular cluster 47 Tucanae, and was previously thought to be a cataclysmic variable. However, Miller-Jones et al. recently identified a radio counterpart to X9 (inferring a radio/X-ray luminosity ratio consistent with black hole LMXBs), and...
