| Abstract: |
During the past decade the parameter space accessible for blazar studies increased markedly. In the regime of temporal coverage fast variability (IDV) on scales of days, hours and minutes was established. In frequency space the 100 keV - 10 TeV regime (8 orders of magnitude) opened up. It is clear now that a full understanding of the physical processes requires variability studies which have dense coverage in time as well as in frequency. While correlations between variations in different parts of the spectrum could be established, it also became clear that the relationship is likely to be more complicated than assumed previously. Recent empirical progress as well as the state of the art of theoretical modeling shall be reviewed. |
