Observing positive and negative AGN feedback
Giovanni Cresci, Roberto Maiolino
TL;DR
This paper reviews observations and simulations of galaxy-scale outflows from active black holes, discussing their complex roles in both suppressing and triggering star formation through a delayed feedback mechanism.
Contribution
It highlights recent evidence supporting a delayed feedback process linking AGN outflows to star formation activity.
Findings
Outflows are associated with both suppression and triggering of star formation.
Recent evidence favors a delayed feedback mechanism.
Simulations support the observational findings.
Abstract
Galaxy-scale outflows powered by actively accreting supermassive black holes are routinely detected, and they have been associated both with suppression and triggering of star formation. Recent observational evidence and simulations are favouring a delayed mechanism that connects outflows and star formation
