AGN PHYSICS IN THE CTA ERA - open workshop on May 16 & 17, 2011

With the start of its Preparatory Phase in 2010, a new step has been made towards the construction of CTA, the future large Cherenkov Telescope Arrayof ground-based gamma-ray astronomy.
A two-day workshop devoted to  "AGN physics in the CTA era" was held in Toulouse, May 16th-17th 2011, in parallel with ageneral meeting of the CTA consortium. This workshop was open to all interested scientists. Combining reviews and contributed talks, the meeting aimed at presenting the current state of the art and at characterizing future observing programmes for the various facets of AGN science at very high energies (VHE). Topics that were discussed included AGN population studies, particle acceleration and VHE emission models, variability studies,  multiwavelength approach, blazar sequence and unification, connection with the EBL and intergalactic magnetic field ...
