FIRST ANNOUNCEMENT ESO Workshop on: "Obscured AGN across Cosmic Time" Seeon, Bavaria, Germany, 5-7 June 2007 http://www.eso.org/agnii2007 SCIENTIFIC RATIONALE Current deep surveys, notably in X-rays and the mid-IR, are making it possible to carry out a census of essentially all the luminous AGN in the universe. By penetrating the obscuration that, in Type 2 sources, hides the nuclear regions in the UV to the near-IR spectrum, these new surveys are finding the radio quiet counterparts of the powerful radio galaxies. The completion of such a census has substantial cosmological significance since it will provide the foundation for identifying the role of AGN feedback in the galaxy formation process. The Type 2 sources are of particular value here since, by acting as their own coronographs, they facilitate the study of the star formation activity and the investigation of the correlated growth of the black hole and the host galaxy. While radio galaxies - which are being used to trace the massive galaxy population at all epochs - have been studied intensively for the past 40 years, their radio quiet counterparts beyond the local universe are only now being discovered in substantial numbers. The workshop aims to bring together the established radio galaxy community with the students of the radio quiet sources and so help to elucidate the effects of the (possibly) different host galaxies and environment and those of the powerful radio jets.
