Multi-wavelength follow-up studies of eruptive cataclysmic variables in the MeerKAT and CTA era

Abstract

Cataclysmic variables (CVs) have been studied for decades, but it is only during recent years that the importance of multi-wavelength studies of these sources have motivated dedicated surveys e.g. CRTS and MASTER. Multi-wavelength follow-up studies are required to fully constrain the properties and radiative processes of CVs, as these sources emit energy over almost the whole electromagnetic spectrum. A selection of results from a multi-wavelength follow-up study of CV systems, showing high levels of transient emission, will be discussed. This will also be used to demonstrate how essential dedicated radio and gamma-ray telescopes like MeerKAT and the forth-coming Cherenkov Telescope Array (CTA) are to complete our understanding of these sources and associated eruptive processes in general. Constraining non-thermal synchrotron emission processes in CVs and high energy outbursts are of special interest.
