Nowhere Left to Hide: Uncovering All of the Massive Young Embedded Star Clusters in the Antennae with JWST
Rupali Chandar, Miranda Caputo, Paul Goudfrooij +15
The Antennae galaxies merger produces the brightest infrared emission of any galaxy within ~20 Mpc, mostly from intense star formation taking place in supergiant molecular cloud co…
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…
SIMLA: The Spitzer Infrared Spectrograph Mapping Legacy Archive
Grant P. Donnelly, Cory M. Whitcomb, Lindsey Hands +9
We present the Spitzer/IRS Mapping Legacy Archive (SIMLA); a complete set of mid-infrared spectral cubes built from low-resolution mapping-mode fixed-target observations from Spitz…
Resolving Emission from Small Dust Grains in the Blue Compact Dwarf II Zw 40 with JWST
Thomas S. -Y. Lai, Sara Duval, J. D. T. Smith +15
We present James Webb Space Telescope (JWST) Near Infrared Spectrograph (NIRSpec) and Mid-infrared Instrument (MIRI) integral-field spectroscopy of the nearby blue compact dwarf II…
The Metallicity Dependence of PAH Emission in Galaxies II: Insights from JWST/NIRCam Imaging of the Smallest Dust Grains in M101
Cory M. Whitcomb, J. -D. T. Smith, Elizabeth Tarantino +11
We explore the physical origins of the observed deficit of polycyclic aromatic hydrocarbons (PAHs) at sub-solar metallicity using JWST/NIRCam imaging of the nearby galaxy M101, cov…
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…
The Metallicity Dependence of PAH Emission in Galaxies I: Insights from Deep Radial Spitzer Spectroscopy
Cory M. Whitcomb, J. -D. T. Smith, Karin Sandstrom +9
We use deep Spitzer mid-infrared spectroscopic maps of radial strips across three nearby galaxies with well-studied metallicity gradients (M101, NGC 628, and NGC 2403) to explore t…
PHANGS-JWST First Results: Mid-infrared emission traces both gas column density and heating at 100 pc scales
Adam K. Leroy, Karin Sandstrom, Erik Rosolowsky +48
We compare mid-infrared (mid-IR), extinction-corrected H, and CO (2-1) emission at 70--160 pc resolution in the first four PHANGS-JWST targets. We report correlation strengths,…
PHANGS-JWST First Results: A Global and Moderately Resolved View of Mid-Infrared and CO Line Emission from Galaxies at the Start of the JWST Era
Adam K. Leroy, Alberto D. Bolatto, Karin Sandstrom +41
We explore the relationship between mid-infrared (mid-IR) and CO rotational line emission from massive star-forming galaxies, which is one of the tightest scalings in the local uni…
PHANGS-JWST First Results: Measuring PAH Properties across the multiphase ISM
Jérémy Chastenet, Jessica Sutter, Karin Sandstrom +26
Ratios of polycyclic aromatic hydrocarbon (PAH) vibrational bands are a promising tool for measuring the properties of the PAH population and their effect on star formation. The ph…
