Abstract (ScienceDirect, SAO/NASA ADS)
We study tachyonic synchrotron densities of ultrarelativistic electrons in helical motion. There is a longitudinally polarized spectral component due to the negative mass square of the superluminal quanta. The helical pitchangle scaling of the transversal and longitudinal spectral densities is investigated, in particular the transition from circular to rectilinear motion. The magnetic field induces oscillations along the powerlaw slopes of the superluminal radiation densities, whose amplitude depends on the pitch angle. At moderate field strength and ultrarelativistic orbital speed, the modulations are tiny, but they become quite pronounced in the surface fields of γray pulsars, resulting in cockscomb distributions. A tachyonic spectral fit to the γray flux of the binary pulsar PSR B1259–63 is performed. The γray wideband of this millisecond pulsar is reproduced by a tachyonic cascade spectrum, capable of generating the spectral curvature in doublelogarithmic plots as well as the extended spectral plateau defined by ISGRI, OSSE, COMPTEL, and EGRET flux points.
