Workshop description

The meeting in Bonn was aimed at bringing together scientists involved in AGN studies in different spectral bands, and discussing the nuclear activity in galaxies from different perspectives and in connection with similar processes occurring in galactic objects (X-ray binaries and "microquasars"). Critical aspects of AGN and XRB research were highlighted in a small number of invited reviews, and further explored in the contributed talks and discussion forums. The workshop was focused on three broadly-defined areas in which various fields of AGN research intersect with each other and with studies of the XRB.

  • AGN across the bands. Different "viewpoints" on AGN, ranging from the radio to the Gamma-ray band. Latest developments in the radio studies of AGN and in the emerging fields of jet and supermassive black hole studies in the optical, X-ray and Gamma-ray domains.
  • AGN across the luminosity range. Reviewing the recent advances in studies of nuclear activity in Seyferts and LINERs and comparing these to the activity observed in powerful AGN. Connection betwen the accretion process and the BH mass/luminosity relation. Production of relativistic outflows and their role in AGN. Theoretical modelling and connection betwen AGN and XRB. Searching for a common phennomenology and physics spanning across orders of magnitude in the parameter space.
  • AGN across the Universe. Co-evolution of AGN and their host galaxies. Connecting the mainstream AGN studies to galaxy formation and evolution, galaxy and black hole mergers and cosmology issues. Role of supermassive binary black holes in the evolution of AGN.

The workshop was attended by 56 scientists and PhD students representing 34 astronomical institutes and universities from 14 different countries.

Sponsorship and Organization

The workshop was sponsored and organized by the EU Consortium RadioNet together with the Max-Planck-Institut für Radioastronomie, as part of the RadioNet Scientific Workshop Program.
