The conference will take place in the impressive historic building of the Center of Mediterranean Architecture of the city of Chania, which is located on the east side of the island of Crete. Convenient access to the island is guaranteed as it can be reached easily with many direct international flights as well as via Athens by air or by boat.

Our understanding of the formation of supermassive black holes at the centres of galaxies has developed significantly in the last years as a result of new observational data and improvements in numerical methods for simulating the growth of black holes within galaxies.

X-ray surveys have proven to be very efficient in finding AGN probing the most heavily obscured as well as the low luminosity AGN. The Chandra Deep Field Surveys yield the highest sky density of AGN ever, a couple of orders of magnitude above that found in QSO optical surveys. At the same time the hard X-ray missions SWIFT/BAT, Integral and mainly Nustar provide the most unbiased AGN surveys in terms of obscuration, easily detecting even the extremes of obscuration the Compton-thick AGN. Spectroscopic X-ray observations mainly with the XMM mission have shown clear evidence of interaction between the supermassive black hole and the host galaxy.

Recently, mid-IR surveys performed by WISE and Spitzer have demonstrated that they can efficiently probe the AGN torus hot dust. Mid-IR diagnostic diagrams and novel Spectral Energy distribution modelling can readily distinguish between AGN and nuclear massive star-formation. As a result the first AGN luminosity functions have been constructed in IR wavelengths.

Optical surveys such as the SDSS despite the fact that they are hampered by obscuration, they are irreplaceable in finding rare AGN such as high redshift AGN because of the large area covered.

All the above observations in couple with models of galaxy formation have brought major developments in the areas of the AGN demography, the unification model, and the studies of the environment in which AGN reside. The future bears exciting developments in the above areas. Large area optical and near-IR surveys (e.g. PANSTARRS, DES, VHS) with very deep magnitude limits can provide insight on the birth of the first AGN and on reddened QSOs. In a couple of years the eROSITA instrument is expected to detect about 3,000,000 AGN bringing a wealth of data for studying the AGN environment and for constraining these number of heavily obscured AGN. ESA’s X-ray mission ATHENA is expect to revolutionise the studies of AGN owing to its superb sensitivity.

It is the aim of this conference to review and discuss the most recent observational and modelling developments on the study of AGN accretion physics, AGN evolution and co-evolution with galaxies.
