Title of the communication: Models for Blazars (Key Note talk)
Preliminary abstract (12 lines max.):
I will review current models for blazars,
concentrating on the sub-parsec scale
region of the jet. Multiwavelength
monitoring observations show that the
emission site is stratified according to
waveband. I will show how the observations
constrain the geometry of this
stratification. I will also discuss models
for explaining the observed light curves of
blazars and try to draw an overall picture
of a blazar that is consistent with the
observations.We present new simulations of relativistic
extragalactic jets, in particular
exploring the pattern of shocks within
diverging flows using extremely long
grids to accommodate the very large
wavelength of such structures. We also
present radiation transfer calculations
incorporating time delay effects.
