We report the discovery of peculiar X-ray spectral variability in the binary radio millisecond pulsar PSR J0024-7204W in the globular cluster 47 Tuc. The observed emission consists of a dominant nonthermal component, which is eclipsed for a portion of the orbit, and a thermal component, which appears to be persistent. We propose that the nonthermal X-rays originate in a relativistic intrabinary shock, formed due to interaction between the relativistic particle wind from the pulsar and matter… Expand

TLDR
An x-ray nebula detected around the binary millisecond pulsar B1957+20 indicates that the efficiency with which relativistic particles are accelerated in the postshock flow is similar to that for young pulsars, despite the shock proximity and much weaker surface magnetic field of this millisecOND pulsar.
