Data from "GA-NIFS: Mapping z~3.5 AGN-driven ionized outflows in the COSMOS field" (Bertola+25)

Active Galactic Nuclei (AGN) are a key ingredient in galaxy evolution, possibly shaping galaxy growth through the generation of powerful outflows. Little is known regarding AGN-driven ionized outflows in moderate-luminosity AGN (logLbol[erg/s]<47) beyond cosmic noon (z>3). We present the first systematic analysis of the ionized outflow properties of a sample of X-ray-selected AGN (logLx[erg/s]>44) from the COSMOS-Legacy field at z~3.5 and with logLbol[erg/s]=45.2-46.7, by using JWST NIRSpec/IFU spectroscopic observations as part of the GA-NIFS program. We spectrally isolate and spatially resolve the ionized outflows, by performing a multi-component kinematic decomposition of the rest-frame optical emission lines. JWST/NIRSpec IFU data also revealed a wealth of close-by companions, of both non-AGN and AGN nature, and ionized gas streams likely tracing tidal structures and large-scale ionized gas nebulae, extending up to the circum-galactic medium. Ionized outflows are detected in all COS-AGN targets, which we compare with previous results from the literature up to z~3, opportunely (re-)computed for a coherent comparison. We normalize outflow energetics ($\dot{M}_{out}$, $\dot{E}_{out}$) to the outflow density to standardize the various assumptions that were made in the literature. Our choice is equal to assuming that each outflow has the same gas density. We find GA-NIFS AGN to show outflows consistent with literature results, within the large scatter shown by the collected measurements, suggesting no strong evolution with redshift in terms of total mass outflow rate, energy budget and outflow velocity for fixed bolometric luminosity. Moreover, we find no clear redshift evolution of the ratio of mass outflow rate and kinetic power over AGN bolometric luminosity beyond z>1. In general, our results indicate no significant evolution of the physics driving outflows beyond z~3. [abridged]
