Feedback in Emerging extragAlactic Star clusTers, FEAST: JWST spots PAH destruction in NGC 628 during the emerging phase of star formation
We investigate the emergence phase of young star clusters in the nearby spiral galaxy NGC 628. We use JWST NIRCam and MIRI observations to create spatially resolved maps of the Pa\(\alpha\)-1.87 \(\mu\)m and Br\(\alpha\)-4.05 \(\mu\)m hydrogen recombination lines, as well as the 3.3 \(\mu\)m and 7.7...

| description | We investigate the emergence phase of young star clusters in the nearby spiral galaxy NGC 628. We use JWST NIRCam and MIRI observations to create spatially resolved maps of the Pa\(\alpha\)-1.87 \(\mu\)m and Br\(\alpha\)-4.05 \(\mu\)m hydrogen recombination lines, as well as the 3.3 \(\mu\)m and 7.7 \(\mu\)m emission from polycyclic aromatic hydrocarbons (PAHs). We extract 953 compact HII regions and analyze the PAH emission and morphology at \(\sim\)10 pc scales in the associated photo-dissociation regions (PDRs). While HII regions remain compact, radial profiles help us to define three PAH morphological classes: compact (\(\sim\) 42%), extended (\(\sim\) 34%) and open (\(\sim\) 24%). The majority of compact and extended PAH morphologies are associated with very young star clusters (\( |

We observe a general decrease in the 3.3 \(\mu\)m and 7.7 \(\mu\)m PAH band emission as a function of cluster age, while their ratio remains constant with age out to 10 Myr and morphological class. The recovered PAH\(_{3.3 \mu{\rm m}}\)/PAH\(_{7.7 \mu{\rm m}}\) ratio is lower than values reported in the literature for reference models that consider neutral and ionized PAH populations and analyses conducted at galactic scales. The 3.3 \(\mu\)m and 7.7 \(\mu\)m bands are typically associated to neutral and ionised PAHs, respectively. While we expected neutral PAHs to be suppressed in proximity of the ionizing source, the constant PAH\(_{3.3 \mu{\rm m}}\)/PAH\(_{7.7 \mu{\rm m}}\) ratio would indicate that both families of molecules disrupt at similar rates in proximity of the HII regions.</description><identifier>EISSN: 2331-8422</identifier><language>eng</language><publisher>Ithaca: Cornell University Library, arXiv.org</publisher><subject>Clusters ; Emission ; Hydrogen recombinations ; James Webb Space Telescope ; Morphology ; Polycyclic aromatic hydrocarbons ; Spiral galaxies ; Star & galaxy formation ; Star clusters ; Star formation</subject><ispartof>arXiv.org, 2024-06</ispartof><rights>2024.
