Although searches so far have been restricted to a few small rockets and balloons, some 40 discrete x-ray sources have already been resolved against a diffuse, nearly isotropic background radiation. The strongest source is about 2000 times as bright as the weakest detectable with present rocket instruments.

The most significant progress in x-ray astronomy in the past few years has been brought about by the advent of satellite observatories and by the great number of new radio and optical identifications of cosmic x-ray sources. Since the discovery, with rocket-borne instruments, of extrasolar sources of x radiation ten years ago, it has been clear to most

Abstract The properties of the X-ray emission from normal stars, i.e., single stars located on the main-sequence or giant branch, are reviewed. Theoretical attempts to explain the observed X-ray emission both from early as well as late type stars are presented and, in particular, coronal length scale determination from spatially unresolved data is ...

AIP Conference Proceedings, 2012
We provide a concise review of X-ray observations of synchrotron and inverse Compton radiation from relativistic electrons in cosmic sources, in the context of synergies between X-ray and γ-ray astronomy. Particular emphasis is placed on the cases of supernova remnants, pulsar wind nebulae, and relativistic jets of quasars.
