Core Revelations: the Star Formation and AGN Connection at the Heart of NGC 7469
Abstract
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. Although it is possible that the star forming ring may inherently not be uniform, 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.
