Abstract
Two energetic hard X-ray bursts have recently triggered the Fermi and Swift
space observatories from the rotation powered pulsar, PSR J1119-6127. We have
performed in depth spectral and temporal analyses of these two events. Our
extensive searches in both observatory data for lower luminosity, untriggered,
bursts using two independent methods (a signal-to-noise ratio search and a
Bayesian blocks based technique), uncovered 10 additional events from the
source. We report here on the timing and energetics of the 12 bursts from PSR
J1119-6127 during its burst active phase of 2016 July 26 and 28. We also found
a softer, extended thermal burst tail emission, which shows evidence of
cooling. We discuss here the implications of these results on the nature of
this unusual high-field radio pulsar, which firmly place it within the typical
magnetar population.
