Afternoon April 22: Welcomes, Introduction, the blazar paradigm presentation
Welcome
Annalisa Celotti : blazars: the broad-band observational point of view
Amir Levinson: Relativistic flows in active galaxies

************************************************************************** Morning April 23, the soft side: radio, IR, optical (photometric and polarimetric variability)
Svetlana Jorstadt: VLBI observations of blazars
Denise Gabuzda: VLBI polarisation variability and implications for jet models
Esko Valtaoja: Total intensity radio variability in blazars
Gino Tosti : IR/optical/UV variability (photometric, spectral,polarization) in blazars
Eric Perlman: thermal AGN signatures in Blazars
************************************************************************** Afternoon April 23, the hard side: soft/hard X-ray, gamma ray and VHE gamma ray reviews
Alan Marscher:Long-term X-ray variability in blazars and its multiwaveband context
Julie McEnery: HE gamma-ray variability, what we know, where we will know more
Wystan Benbow: Very High Energy variability (flux, spectral) - what we have learned
************************************************************************** Morning April 24: (end of previous session) presentations on analysis tools (linear, non-linear)
Robert Wagner: Correlations within/between the two radiative populations
Ian McHardy: aperiodic variability and emission processes, from BHs to SMBHs
Jun Kataoka: How to Characterize aperiodic variability (PDS, structure functions, ..): (use cases, biases ) with synchrotron radiation
Bernard Degrange: How to Characterize aperiodic variability (PDS, structure functions, PDS:use cases, biases) at very high energies
******************************************************************************* Afternoon April 24: mechanisms at play and their inherent variability
John Kirk: particle acceleration mechanisms and variability in relativistic flows (stochastic processes, shocks, magnetic reconnection, matter/radiation dominated scenarios)
Gilles Henri: A unified time-dependant view of relativistic jets
Chuck Dermer/ Justin Fink: Multiwavelength Synchrotron/Compton Spectral Analysis of TeV Blazars and FSRQs: A New Approach
R Moderski: Radiative outputs from blazars (radiative processes, escape, light crossing, KN effects, emphasis on what we learn from the synchrotron bump about the underlying particle distributions).
Stefan Wagner: propagation effects in VHE gamma-rays: the physics, how to find them (e.g. Quantum gravity effects, Lorentz invariance violations..)
******************************************************************************* Morning April 25: What will future instruments improve, which measurements do we need, summary talk
Hélene Sol: Unification scenarios: the case of M87
Greg Madejski: The next generation of space-based observatories (nuStar, Constellation X, ..) and their potential for variability determinations
Michael Punch: Strengths and limitations of ACTs (present and future) for transient VHE sources
Philip Kaaret: Summary talk, what have we learned, outstanding questions
