## TL;DR

This study provides the first spatially resolved analysis of outflows in a high-redshift Seyfert galaxy, revealing AGN-driven outflows with minimal impact on star formation, thanks to gravitational lensing and adaptive optics.

## Contribution

It offers a detailed spatial examination of AGN outflows at cosmic noon using gravitational lensing and adaptive optics, a novel approach for such distant galaxies.

## Key findings

- AGN-driven outflows are present with broad emission line components.
- The outflows are consistent with AGN ionization diagnostics.
- The AGN does not significantly suppress star formation in the host galaxy.

## Abstract

We present the first spatially resolved analysis of rest-frame optical and UV imaging and spectroscopy for a lensed galaxy at z = 2.39 hosting a Seyfert active galactic nucleus (AGN). Proximity to a natural guide star has enabled high signal-to-noise VLT SINFONI + adaptive optics observations of rest-frame optical diagnostic emission lines, which exhibit an underlying broad component with FWHM ~ 700 km/s in both the Balmer and forbidden lines. Measured line ratios place the outflow robustly in the region of the ionization diagnostic diagrams associated with AGN. This unique opportunity - combining gravitational lensing, AO guiding, redshift, and AGN activity - allows for a magnified view of two main tracers of the physical conditions and structure of the interstellar medium in a star-forming galaxy hosting a weak AGN at cosmic noon. By analyzing the spatial extent and morphology of the Ly-alpha and dust-corrected H-alpha emission, disentangling the effects of star formation and AGN ionization on each tracer, and comparing the AGN induced mass outflow rate to the host star formation rate, we find that the AGN does not significantly impact the star formation within its host galaxy.
