Multifrequency observations of non-magnetic cataclysmic variables.
The authors review the multifrequency behaviour of the so-called non-magnetic cataclysmic variables (NMCVs) after having discussed the classification of the CVs...
Multifrequency Variability and Correlations from Extensive Observing Campaigns of Mkn 421 and Mkn 501 in 2009
We are performing an unprecedentedly long and dense monitoring of the multi-frequency (radio to TeV) emission from the classical TeV blazars Mkn 421 and Mkn 501...
