Flares, Fields and Filaments of the Guitar Nebula

Pulsar filaments are linear structures showing X-ray synchrotron emission extending upstream from surrounding shock fronts into the general ISM. One infers that the pulsar provides the multi-TeV e+/e- lighting up the filaments and that the particles are initially ducted by an external magnetic field. The Guitar is one of the most visually striking examples, with an Hα bow shock, a sharp leading filament and trailing diffuse emission. We describe new HST/Chandra/Robopol observations which show that the structure is dynamic, probing the impulsive flares that light up the filament, the ISM magnetic fields that direct the e+/e- cosmic rays and the diffusion effects that spread them into the ISM.
