Despite extraordinary spin-down power, the inferred gamma-ray efficiency is extremely low, giving researchers a new case for testing particle acceleration and beam geometry. The result is reported in an arXiv preprint and has not yet completed journal peer review; the fiber-optic image is only a signal metaphor.",
