Growth of Aromatic Hydrocarbon Dust Particles in the Extremely Metal-poor Galaxy Sextans A
Elizabeth J. Tarantino, Julia Roman-Duval, Karin M. Sandstrom +17
The mid-infrared spectrum of star-forming, high metallicity galaxies is dominated by emission features from aromatic and aliphatic bonds in small carbonaceous dust grains, often re…
Resolved HII regions in NGC 253: Ionized gas structure and suggestions of a universal density-surface brightness relation
Rebecca L. McClain, Adam K. Leroy, Enrico Congiu +23
We use the full-disk VLT-MUSE mosaic of NGC 253 to identify 2492 HII regions and study their resolved structure. With an average physical resolution of 17 pc, this is one of the la…
Resolved Profiles of Stellar Mass, Star Formation Rate, and Predicted CO-to-H Conversion Factor Across Thousands of Local Galaxies
Jiayi Sun, Yu-Hsuan Teng, I-Da Chiang +9
We present radial profiles of surface brightness in UV and IR bands, estimate stellar mass surface density () and star formation rate surface density (), a…
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…
Characterization of Two Cool Galaxy Outflow Candidates Using Mid-Infrared Emission from Polycyclic Aromatic Hydrocarbons
Jessica Sutter, Karin Sandstrom, Ryan Chown +22
We characterize two candidate cool galactic outflows in two relatively low mass, highly inclined Virgo cluster galaxies: NGC4424 and NGC4694. Previous analyses of observations usin…
The radial variation of the silicate-to-carbon ratio in M31 probed by PRIMA
Jérémy Chastenet, Ilse De Looze, Maarten Baes +12
The properties of interstellar dust grains are being scrutinized more than ever before, with the advent of large facilities. Infrared emission from dust grains is a powerful asset…
The PRIMA promise of deciphering interstellar dust evolution with observations of the nearby Universe
Frédéric Galliano, Maarten Baes, Léo Belloir +25
This paper develops a few science cases, using the PRIMA far-IR probe, aimed at achieving several breakthroughs in our understanding of the dust properties and their evolution. We…
Relationships between PAHs, Small Dust Grains, H, and HI in Local Group Dwarf Galaxies NGC 6822 and WLM Using JWST, ALMA, and the VLA
Ryan Chown, Adam K. Leroy, Alberto D. Bolatto +27
We present 0.7-3.3 pc resolution mid-infrared (MIR) JWST images at 7.7 m (F770W) and 21 m (F2100W) covering the main star-forming regions of two of the closest star-forming l…
The Resolved Structure of a Low Metallicity Photodissociation Region
Ilyse Y. Clark, Karin Sandstrom, Mark Wolfire +14
Photodissociation Regions (PDRs) are key to understanding the feedback processes that shape interstellar matter in galaxies. One important type of PDR is the interface between HII…
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…
A Catalog of Stellar and Dust Properties for 500,000 Stars in the Southwest Bar of the Small Magellanic Cloud
Petia Yanchulova Merica-Jones, Karl Gordon, Karin Sandstrom +8
We present a catalog of individual stellar and dust extinction properties along close to 500,000 sight lines in the southwest bar of the Small Magellanic Cloud (SMC). The catalog i…
