NuSTAR and XMM-Newton Observations of PSR J1930+1852 and Its Pulsar Wind Nebula
The Astrophysical JournalSynchrotron X-ray emission from a pulsar wind nebula (PWN) is a sensitive probe of its magnetic field and high-energy particle population. Here we analyze contemporaneous NuSTAR and XMM - Newton observations of the PWN G54.1+0.3, powered by pulsar PSR ...

A corrugated termination shock in pulsar wind nebulae? [PDF]
Journal of Plasma Physics, 2016 Successful phenomenological models of pulsar wind nebulae assume efficient dissipation of the Poynting flux of the magnetized electron–positron wind as well as efficient acceleration of the pairs in the vicinity of the termination shock, but how this is realized is not yet well understood.
