Ashes of Creation: JWST Uncovers Silicate Dust in Massive Star Clusters
Daniel Maschmann, Bradley C. Whitmore, David A. Thilker +35
Dust production is a fundamental aspect of the baryonic cycle of star formation. It is known that dust is injected into the interstellar medium during early star formation by super…
PAH Marks the Spot: Digging for Buried Clusters in Nearby Star-forming Galaxies
Gabrielle B. Graham, Daniel A. Dale, Chase L. Smith +39
The joint capabilities of the Hubble Space Telescope (HST) and JWST allow for an unparalleled look at the early lives of star clusters at near- and mid-infrared wavelengths. We pre…
Masses, Star-Formation Efficiencies, and Dynamical Evolution of 18,000 HII Regions
Debosmita Pathak, Adam K. Leroy, Ashley. T. Barnes +36
We present measurements of the masses associated with HII regions across 19 nearby star-forming galaxies by combining data from JWST, HST, MUSE, ALMA, VLA, and MeerKAT…
Polycyclic aromatic hydrocarbons destruction in star-forming regions across 42 nearby galaxies
Oleg V. Egorov, Adam K. Leroy, Karin Sandstrom +30
Polycyclic aromatic hydrocarbons (PAHs) are widespread in the interstellar medium (ISM) of Solar metallicity galaxies, where they play a critical role in ISM heating, cooling, and…
The Hidden Life of Stars: Embedded Beginnings to AGB Endings in the PHANGS-JWST Sample. I. Catalog of Mid-IR Sources
Hamid Hassani, Erik Rosolowsky, Adam K. Leroy +28
We present a multiwavelength catalog of mid-infrared-selected compact sources in 19 nearby galaxies, combining JWST NIRCam/MIRI, HST UV-optical broadband, H narrow-band, and ALM…
Time-scales of polycyclic aromatic hydrocarbon and dust continuum emission from gas clouds compared to molecular gas cloud lifetimes in PHANGS-JWST galaxies
Jaeyeon Kim, Mélanie Chevance, Lise Ramambason +24
Recent JWST mid-infrared (mid-IR) images, tracing polycyclic aromatic hydrocarbons (PAHs) and dust continuum emission, provide detailed views of the interstellar medium (ISM) in ne…
Empirical SED Templates for Star Clusters Observed with HST and JWST: No Strong PAH or IR Dust Emission after Five Myr
Bradley C. Whitmore, Rupali Chandar, Janice C. Lee +25
JWST observations, when combined with HST data, promise to improve age estimates of star clusters in nearby spiral galaxies. However, feedback from young cluster stars pushes out t…
PAH Feature Ratios Around Stellar Clusters and Associations in 19 Nearby Galaxies
Daniel A. Dale, Gabrielle B. Graham, Ashley T. Barnes +27
We present a comparison of observed polycyclic aromatic hydrocarbon (PAH) feature ratios in 19 nearby galaxies with a grid of theoretical expectations for near- and mid-infrared du…
