Discovery of Gamma-Ray Pulsations from the Millisecond Pulsar PSR J0435+3233

Motivated by the discovery of PSR J0435+3233, a millisecond pulsar (MSP) with an exceptionally large observed period derivative of Ṗ=4.9×10−17ss−1 and a nominal spin-down luminosity of Ėnom=5.89×1037ergs−1 , we analyze ∼17.7 yr of Fermi-LAT data. We identify the cataloged source 4FGL J0435.5+3232, located only ∼0 .°...
