The Experiment: AGN and galaxy evolution
- A small fraction of galaxies contain an “Active Nucleus” (AGN) ? probably a supermassive black hole ? gas falls towards BH (accretion) ? energy
- AGN in some emits two jets of plasma ? interact strongly with their environment
- Immense power of AGN ? do the modify evolution of galaxy
High resolution telescopes to probe the working of the AGN
