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…

Feature Intensity Mapping: Polycyclic Aromatic Hydrocarbon Emission from All Galaxies Across Cosmic Time
Yun-Ting Cheng, Brandon S. Hensley, Thomas S. -Y. Lai
Line intensity mapping (LIM) is an emerging technique for probing the aggregate emission of a spectral line from all sources, without requiring individual detections. Through the w…

Mapping Galactic Dust Emission and Extinction with HI, HII, and H
Yun-Ting Cheng, Brandon S. Hensley, Tzu-Ching Chang +1
Neutral hydrogen (HI) emission closely traces the dust column density at high Galactic latitudes and is thus a powerful tool for predicting dust extinction. However, the relation b…
