Globular cluster x-ray sources
@article{Pooley2010GlobularCX, title={Globular cluster x-ray sources}, author={David Pooley}, journal={Proceedings of the National Academy of Sciences}, year={2010}, volume={107}, pages={7164 - 7167} }
Globular clusters and x-ray astronomy have a long and fruitful history. Uhuru and OSO-7 revealed highly luminous (> 1036 ergs-1) x-ray sources in globular clusters, and Einstein and ROSAT revealed a larger population of low-luminosity (< 1033 ergs-1) x-ray sources. It was realized early on that the high-luminosity sources were low-mass x-ray binaries in outburst and that they were orders of magnitude more abundant per unit mass in globular clusters than in the rest of the galaxy. However, the…
