JWST Whirlpool Galaxy Treasury: Mid-Infrared Emission in M51 and its Relation to Gas Column and Star Formation
Mansi Padave, Karin M. Sandstrom, Daniel A. Dale +25
Using JWST/MIRI imaging of M51 in eight broadband filters, we investigate correlations of mid-infrared emission from polycyclic aromatic hydrocarbons (PAHs) and dust continuum with…
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…
The HII Regions' Molecular Law of Star Formation
Daniela Calzetti, Drew Lapeer, Robert C. Kennicutt +28
We combine imaging data from the HST, JWST, and ground-based millimeter facilities to investigate the correlation between star formation rate (SFR) and molecular gas at the ~100 pc…
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…
Localized Deviations from the CO-PAH Relation in PHANGS-JWST Galaxies: Faint PAH Emission or Elevated CO Emissivity?
Jaeyeon Kim, Adam K. Leroy, Karin Sandstrom +25
Polycyclic aromatic hydrocarbon (PAH) emission is widely used to trace the distribution of molecular gas in the interstellar medium, exhibiting a tight correlation with CO(2-1) emi…
The PHANGS-MUSE/HST-Halpha Nebulae Catalogue
A. T. Barnes, R. Chandar, K. Kreckel +38
We present the PHANGS-MUSE/HST-Halpha nebulae catalogue, comprising 5177 spatially resolved nebulae across 19 nearby star-forming galaxies (< 20 Mpc), based on high-resolution Halp…
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…
Quantification of The Age Dependence of Mid-Infrared Star Formation Rate Indicators
Daniela Calzetti, Robert C. Kennicutt, Angela Adamo +33
We combine James Webb Space Telescope images of the nearby galaxy NGC 5194 in the hydrogen recombination line Pa-alpha (lambda=1.8756 micron) from the Cycle 1 program JWST-FEAST wi…
Duration and properties of the embedded phase of star formation in 37 nearby galaxies from PHANGS-JWST
Lise Ramambason, Mélanie Chevance, Jaeyeon Kim +32
Light reprocessed by dust grains emitting in the infrared allows the study of the physics at play in dusty, embedded regions, where ultraviolet and optical wavelengths are attenuat…
Detection of Deuterated Hydrocarbon Nanoparticles in the Whirlpool Galaxy, M51
B. T. Draine, Karin Sandstrom, Daniel A. Dale +29
Deuteration of hydrocarbon material, including polycyclic aromatic hydrocarbons (PAHs), has been proposed to account for the low gas-phase abundances of D in the interstellar mediu…
An Investigation of Disk Thickness in M51 from H-alpha, Pa-alpha, and Mid-Infrared Power Spectra
Bruce G. Elmegreen, Daniela Calzetti, Angela Adamo +27
Power spectra (PS) of high-resolution images of M51 (NGC 5194) taken with the Hubble Space Telescope and the James Webb Space Telescope have been examined for evidence of disk thic…
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…
