Searching for the Shortest-wavelength Aromatic Infrared Bands: No Evidence for the Predicted 1.05 m Polycyclic Aromatic Hydrocarbon Feature
Dennis Lee, Brandon S. Hensley, Tzu-Ching Chang +1
Polycyclic aromatic hydrocarbons (PAHs) are responsible for a variety of near- and mid-infrared spectral features in Galactic and extragalactic sources. A feature at 1.05 m ari…

SOFIA Polarization Spectrum of Three Star-Forming Clouds
Erin G. Cox, Giles Novak, David T. Chuss +6
The dust emission polarization spectrum -- how the polarization percentage changes with wavelength -- serves as a probe of dust grain properties in star-forming regions. In this pa…

The End of the Road for Far-infrared Reddening Maps? Evidence for Reddening Errors Driven by Changes in PAH Abundance
Dennis Lee, Brandon S. Hensley, Tzu-Ching Chang +1
Accurate correction for extinction by Galactic dust is essential for studying the extragalactic sky. In the low-extinction regions of the Ursa Major molecular cloud complex, we dem…
