TLDR
In this article, the rapidly evolving synchrotron radiation power spectrum emitted by a single electron can give a radiation continuum with a spectral index having a unique value similar to that observed in the optical and low-energy X-ray regions.Abstract:
We suggest that if there exist within the Crab Nebula localised condensations of material containing high magnetic fields, (» 1 G), the rapidly evolving synchrotron radiation power spectrum emitted by a single electron can give a radiation continuum with a spectral index having a unique value similar to that observed in the optical and low-energy X-ray regions. One implication of this result is that a simple comparison between the observed fluxes of optical and gamma radiation emitted by the Nebula is no longer meaningful, so that one cannot draw any immediate conclusion regarding the fundamental mechanism of electron and gamma ray production.read more

Incoherent Synchrotron Spectra
TL;DR: In this paper, the authors discuss incoherent synchrotron spectra and show that when the magnetic field and electron density in a source increases with radius out to an edge where they are abruptly truncated, the spectrum differs very little from that of a uniform source.

Lunar Occultation of X-ray Emission from the Crab Nebula.
TL;DR: The x-ray flux from the Crab Nebula was observed during a lunar occultation on 7 July 1964 and the source appears to extend over a volume about 1 light-year in diameter.

Synchrotron emission at strong radiative damping.
TL;DR: Synchrotron emission of relativistic particle in magnetic field with radiative reaction force comparable to Lorentz force, emphasizing pulsar cosmic ray electron acceleration as mentioned in this paper, is shown in Fig. 1.

Common Features of the Optical Continua associated with Violent Cosmic Events
TL;DR: In this paper, the authors point out a similarity in the optical continua of several objects associated with violent events, but which otherwise have a diverse character, including the nucleus of the Seyfert Galaxy NGC 4151, the galactic, nova-like object η Carinae, the Crab Nebula and the quasi-stellar radio source 3C748.
