The Lifecycle and Emission Properties of PAHs in Cosmological Hydrodynamic Galaxy Formation Simulations
Desika Narayanan, Paul Torrey, Massimiliano Parente +16
We present the first cosmological model for the lifecycle and luminous properties of PAHs in galaxies as they evolve from z=6-->0. We model 40 zoom-in galaxies, coupled with an on-…
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…
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 SG-WISE View of Global Star Formation in the Nearby Universe
M. E. Cluver, T. H. Jarrett, D. A. Dale +9
In this work we present source-tailored WISE mid-infrared photometry (at 3.4m, 4.6m, 12m, and 23m) of 2812 galaxies in the extended Spitzer Survey of Stellar Structure…
