The X-ray structure of the crab nebula
Abstract
The Einstein Observatory telescope was the first imaging instrument with sufficient spatial resolution to yield X-ray images of the central region of the Crab Nebula. For the deconvolution of this data, a Fourier transform is used which makes visible the ring-like structure of the emission region, including the central hole known from the optical image. The Exosat LE experiment has offered the further opportunity of obtaining X-ray images of the Crab Nebula, with moderate energy resolution, by way of filter spectroscopy. A light curve has been derived from these data, together with pulse fluxes.
