- A multiwavelength perspective

Actively accreting supermassive black holes (SMBHs) are a crucial phase in the formation and evolution of galaxies. The strong emission of the active galactic nucleus (AGN), from the X-ray to the radio, often outshines their host galaxy, making them the most luminous non-transient light sources in the Universe.
AGN science is not only limited to the formation and evolution of SMBHs across cosmic time, but the immense energy released in the accretion process is known to shape its host galaxy and therefore influence galaxy evolution as a whole.
Three central, broad questions have been and are still at the core of AGN science:
  • How do the first supermassive black holes form and grow with time?
  • What processes drive gas from galaxy scales to the central black hole, fueling black hole accretion?
  • How do outflows driven by the AGN couple to the host galaxy and to galaxy cluster environments?
Recent state-of-the-art instrumentation (e.g. MUSE, eRosita, ALMA, LOFAR) along with wide field surveys (e.g. SDSS) are now producing exciting data sets on single objects and on large samples.
In this splinter session we aim to discuss the recent progress in the field based on observational and theoretical studies of AGN, ranging from nearby Seyfert galaxies up to quasars in the epoch of reionization. However, we also want to look forward and explore AGN science in light of future developments.
Surveys (e.g. LSST) and facilities (e.g. JWST, Euclid, 4MOST, SKA, E-ELT) going on-line within the next decade will provide an unprecedented wealth of information to tackle the central science questions from different and exciting angles. To interpret these upcoming data sets, simulations and theoretical models that describe accretion and feedback processes at all scales are vital.
