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…
