Galaxy Evolution and Feedback across Different Environments (IAU S359)

IAU Symposium 359 brings together the active galactic nuclei (AGN) and galaxy evolution scientific communities, to share their knowledge on these processes. They address questions relating to gas acquisition, the fueling of supermassive black holes, AGN feedback processes and the role of a galaxy's environment on its evolution.

The goal of IAU Symposium 359 on 'Galaxy Evolution and Feedback across Different Environments' (GALFEED) was to bring together the active galactic nuclei (AGN) and galaxy evolution scientific communities. The AGN phase occurs in most galaxies and critically influences their evolution, so it is important to study the two processes together and for researchers, in both topics, to learn from one another. They ask key questions such as: How do galaxies acquire their gas and how efficiently is it transformed into stars? How is the supermassive black hole in a galaxy center fuelled to become an AGN? What is the main physical mechanism that quenches star formation? How powerful are the stellar and AGN feedback processes in regulating galaxy evolution? And what is the role of the environment on galaxy evolution and AGN triggering? Astronomers engage in these discussions spanning from early galaxies to the present day.
