Broadband pulsations from PSR B1821-24: Implications for emission models and the pulsar population of M28

We report a 5.4δ detection of pulsed gamma rays from PSR B1821-24 in the globular cluster M28 using ~44 months of Fermi Large Area Telescope (LAT) data that have been reprocessed with improved instrument calibration constants. We constructed a phase-coherent ephemeris, with post-fit residual rms of...
