    • Fermi detection of a luminous y-ray pulsar in a globular cluster 

      Freire, P.C.C.; Venter, C.; Abdo, A.A.; Ajello, M.; Allafort, A.; Fermi LAT (AAAS, 2011)
      We report on the Fermi Large Area Telescope’s detection of γ-ray (>100 mega–electron volts) pulsations from pulsar J1823–3021A in the globular cluster NGC 6624 with high significance (∼7 σ). Its γ-ray luminosity, Lγ = (8.4 ...
