A Three-Millisecond Pulsar Blinked in Gamma Rays
Seventeen years of Fermi data revealed phase-linked gamma emission from an unusually powerful, inefficient millisecond pulsar.
Summary
Seventeen years of Fermi data revealed phase-linked gamma emission from an unusually powerful, inefficient millisecond pulsar.
Astronomers analyzing 17.7 years of Fermi Large Area Telescope observations detected gamma-ray pulsations aligned with the 3.2-millisecond spin of PSR J0435+3233, a binary pulsar roughly 3,900 light-years away. 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.
