Spatially Resolved Active Galactic Nucleus Ionization and Star Formation at Cosmic Noon with JWST/JEMS
At cosmic noon (z ≈ 2–3), both star formation and active galactic nucleus (AGN) activity peaked, each playing a significant role in ionizing interstellar gas on galaxy-wide scales. The spatial distribution of this ionized gas provides a direct probe of how AGN and stellar ionization influence the gaseous reservoirs of...
