DOIAbstract
We report the Fermi Large Area Telescope detection of γ-ray (>100 MeV) pulsations from pulsar J1823−3021A in the globular cluster NGC 6624 with high significance (∼7 σ). Its γ-ray luminosity Lγ = (8.4 ±1.6) × 1034 erg s−1 is the highest observed for any millisecond pulsar (MSP) to date, and it accounts for most of the cluster emission. The nondetection of the cluster in the off-pulse phase implies that it contains <32 γ-ray MSPs, not ∼100 as previously estimated. The γ-ray luminosity indicates that the unusually large rate of change of its period is caused by its intrinsic spin-down. This implies that J1823−3021A has the largest magnetic field and is the youngest MSP ever detected and that such anomalous objects might be forming at rates co...
