Core Revelations: the Star Formation and AGN Connection at the Heart of NGC 7469
We investigate the star formation-AGN connection in the Seyfert 1 NGC 7469
using James Webb Space Telescope (JWST) mid-infrared spectroscopic integral
field unit (IFU) data. We use the IFU data to generate maps of different
emission lines present in the spectrum, such as the star-formation (SF) tracer
[Ne II] 12.81{\mu}m, or the AGN tracer [Ne V] 14.32{\mu}m. We can separate the
AGN- and SF-dominated regions using spatially resolved mid-IR diagnostic
diagrams, and further investigate the ionization sources powering each region
by constructing photoionization models. We find that the previously detected
eastern wind populates an intermediary region of the diagrams, between our
star-forming and AGN quadrants. This wind also coincides with a reduction in
the [Ne II] emission in the ring, which suggests that the ionization cone
intersects the ring in this direction. In spite of this evidence of negative
AGN feedback, given the narrow opening angle of the ionization cone and its
orientation, this would not be a case of efficient feedback.
