Gamma-ray pulsations detected from PSR J0435+3233, an unusually extreme millisecond pulsar

A team led by Mengqing Zhang (Yunnan University) has detected gamma-ray pulsations from PSR J0435+3233, a binary millisecond pulsar at 3,900 light-years with a spin period of 3.2 ms, extraordinary spin-down power, and a gamma-ray efficiency of only ~10⁻⁵ — an outlier in nearly every diagnostic used to classify millisecond pulsars.
