Gamma-Ray Modes in a Transitional Pulsar
Transitional millisecond pulsars (tMSPs) exhibit a unique subluminous disk state, at the crossroads between accretion and rotation power, where they switch between two distinct X-ray modes. We present the discovery of gamma-ray modes in PSR J1023+0038, the first confirmed tMSP, from stacking Fermi-LAT data during the modes (which we identify using simultaneous X-ray observations).
