Feedback in emerging extragalactic star clusters, FEAST: The relation between 3.3 $\mu$m PAH emission and Star Formation Rate traced by ionized gas in NGC 628

Benjamin Gregg, Daniela Calzetti, Angela Adamo +23

We present maps of ionized gas (traced by Pa$\alpha$ and Br$\alpha$) and 3.3 $\mu$m Polycyclic Aromatic Hydrocarbon (PAH) emission in the nearby spiral galaxy NGC 628, derived from new JWST/NI…
