Variations in the 3.3 m Polycyclic Aromatic Hydrocarbon Feature Across Nearby Galaxies Driven by Metallicity and Radiation Field Spectrum
Hannah B. Koziol, Karin Sandstrom, Dalya Baron +29
We use JWST NIRCam imaging to investigate the 3.3 m polycyclic aromatic hydrocarbon (PAH) feature in nearby galaxies. NIRCam observations of the 3.3 m feature are emerging as…
Mid-Infrared Colors Vary with Galactic Environment: Contrasting Star-Forming Disks, Young Centers, and Quiescent Star-Formation Deserts
Debosmita Pathak, Karin M. Sandstrom, Adam K. Leroy +27
We present pc-resolution JWST/MIRI and NIRCam measurements of mid-infrared (mid-IR) color variations in the diffuse interstellar medium (ISM) of 71 nearby star-forming…
The EDGE-CALIFA Survey: Star Formation Efficiency and Galaxy Quenching across 62 Main Sequence, Green Valley, and Red Galaxies
Yu-Hsuan Teng, Alberto D. Bolatto, Peter J. Teuben +26
We present GBT-EDGE, a new CO(1-0) survey using the Green Bank Telescope to map 62 nearby (10-140 Mpc) galaxies spanning the star-forming main sequence (SFMS), green valley, and re…
Survival of very small carbonaceous dust grains in the inner-CGM of NGC 891 from JWST/MIRI MRS
Jérémy Chastenet, Ilse De Looze, Karl D. Gordon +26
We present new spectroscopic observations of the inner circumgalactic medium (CGM) of NGC 891 taken with the Mid-Infrared Imager/Medium Resolution Spectroscopy instrument onboard J…
JWST Observations of Starbursts: Molecular Hydrogen Excitation and Disequilibrium in M82
Sara E. Duval, J. D. T. Smith, Alberto D. Bolatto +24
Emission from the pure rotational transitions of H traces warm molecular gas, providing insight into its temperature distribution and local heating conditions. We have extended…
JWST Observations of Starbursts: Dust Processing in the M82 Superwind
Serena A. Cronin, Alberto D. Bolatto, Helena M. Richie +39
We present JWST MIRI and NIRCam imaging of the inner ~5 kpc of the M82 superwind at 0.05-0.375'' (~0.9-6.5 pc) resolution. Targeted filters probe emission from polycyclic aromatic…
