  Rotation-powered pulsars and magnetars are two different observational
manifestations of neutron stars: rotation powered pulsars are rapidly spinning
objects that are mostly observed as pulsating radio sources, while magnetars,
neutron stars with the highest known magnetic fields, often emit short-duration
X-ray bursts. Here we report simultaneous observations of the
high-magnetic-field radio pulsar PSR J1119-6127 at X-ray, with XMM-Newton &
NuSTAR, and at radio energies with Parkes radio telescope, during a period of
magnetar-like bursts. The rotationally powered radio emission shuts off
coincident with the occurrence of multiple X-ray bursts, and recovers on a time
scale of ~70 seconds. These observations of related radio and X-ray phenomena
further solidify the connection between radio pulsars and magnetars, and
suggest that the pair plasma produced in bursts can disrupt the acceleration
mechanism of radio emitting particles.
