I think that'll turn out to be recognised as a landmark discovery for the field. Note the way the X-ray emission interleaves with the radio pulsing : one or the other at any given time. Which neatly explains why it has been so difficult to confirm the recycling hypothesis in actual examples, and thus the 'Death Valley' region of the pulsar population plots is not so dead after all. For those pulsars which have spun down from birth, some are in binary systems and some of those may evolve to where mass transfer occurs, an accretion disc forms which ( plus or minus x-ray emission in our direction too ) can spin the pulsar up again. Sometimes the companion goes supernova after assisting the spin-up and kicks said pulsar out and about, thus a disrupted recycled pulsar results.
Cheers, Mike.

Validates the recycling scenario of millisecond pulsars :

Good catch ! :-)
