We review the processes and conditions that lead to the production of non-thermal radiation in cataclysmic variables (CVs). We focus on the cases when such emission was really observed in various spectral bands, from gamma rays including TeV emission to radio. Detection of this radiation suggests the presence of highly energetic particles in these CV systems. Synchrotron and cyclotron...

Supernova remnants, owing to their strong shock waves, are likely sources of Galactic cosmic rays. Studies of supernova remnants in X-rays and gamma rays provide us with new insights into acceleration of particles to high energies. I will review the basic physics of supernova remnant shocks and associated particle acceleration and radiation processes. In addition, the study of supernova...

The supernova remnant RX J0852.0-4622, also called by its nickname Vela Jr., was discovered in X-rays by ROSAT. Gamma-rays from the radioactive decay have been reported as well. The combination of the X-ray and gamma-ray measurements allows a fairly precise determination of distance (200 pc) and age (680 yrs). However, later on, the gamma-ray measurements were heavily disputed, so that...

Results from Suzaku observations of clusters of galaxies are reviewed, particularly from the point of view of gas heating and constraint on non-thermal emission from merging clusters.
