On the duration of the embedded phase of star formation
Jaeyeon Kim, Mélanie Chevance, J. M. Diederik Kruijssen +23
Feedback from massive stars plays a key role in molecular cloud evolution. After the onset of star formation, the young stellar population is exposed by photoionization, winds, sup…
Resolving the Dust-to-Metals Ratio and CO-to-H Conversion Factor in the Nearby Universe
I-Da Chiang, Karin M. Sandstrom, Jérémy Chastenet +8
We investigate the relationship between the dust-to-metals ratio (D/M) and the local interstellar medium environment at ~2 kpc resolution in five nearby galaxies: IC342, M31, M33,…
Excitation of Polycyclic Aromatic Hydrocarbon (PAH) Emission: Dependence on Size Distribution, Ionization, and Starlight Spectrum and Intensity
B. T. Draine, Aigen Li, Brandon S. Hensley +3
Using physical models, we study the sensitivity of polycyclic aromatic hydrocarbon (PAH) emission spectra to the character of the illuminating starlight, to the PAH size distributi…
Three-Dimensional Structure and Dust Extinction in the Small Magellanic Cloud
Petia Yanchulova Merica-Jones, Karin M. Sandstrom, L. Clifton Johnson +6
We examine the three-dimensional structure and dust extinction properties in a ~ 200 pc 100 pc region in the southwest bar of the Small Magellanic Cloud (SMC). We model a…
Measuring the mixing scale of the ISM within nearby spiral galaxies
Kathryn Kreckel, I-Ting Ho, Guillermo A. Blanc +28
The spatial distribution of metals reflects, and can be used to constrain, the processes of chemical enrichment and mixing. Using PHANGS-MUSE optical integral field spectroscopy, w…
Mapping the Escape Fraction of Ionizing Photons Using Resolved Stars: A Much Higher Escape Fraction for NGC 4214
Yumi Choi, Julianne J. Dalcanton, Benjamin F. Williams +6
We demonstrate a new method for measuring the escape fraction of ionizing photons using Hubble Space Telescope imaging of resolved stars in NGC 4214, a local analog of high-redshif…
