GA-NIFS: The cosmic evolution of AGN outflows up to z~3-6 with JWST NIRSpec
The period between z~3-6 is a crucial transitional phase in galaxy evolution, leading to "cosmic noon" (z~1-3). A key actor in this phase is expected to be AGN feedback acting through energetic radiation and fast gas outflows. However, little is known so far about AGN feedback at these redshifts. I will present our study of AGN outflows at z~3-6 from GOODS-S and COSMOS fields, the largest spatially resolved sample to date (16 targets), exploiting JWST NIRSpec IFU observations from the GA-NIFS GTO survey. We found an outflow incidence of ~80%, significantly higher than in most AGN samples at lower redshifts. By mapping the rest-optical ionised gas emission lines ([OIII], Ha…) at sub-kpc scales, we inferred the outflow properties (kinematics, energetics) and probed their relations with AGN luminosity and galaxy star formation rate, and compared them with literature studies at different redshifts and AGN luminosities. We find evidence for a cosmic evolution of the outflow properties, indicating that outflows were stronger in the early Universe than at later times, and more capable of affecting their host galaxy evolution.
