NON-THERMAL EMISSION FROM CATACLYSMIC VARIABLES: IMPLICATIONS ON ASTROPARTICLE PHYSICS
We review the lines of evidence that some cataclysmic variables (CVs) are the sources of non-thermal radiation.It was really observed in some dwarf novae in outburst, a novalike CV in the high state, an intermediate polar, polars, and classical novae (CNe) during outburst.The detection of this radiation suggests the presence of highly energetic par
