The Quasar-associated 2175 Å Dust Absorbers in the SDSS DR16 Quasar Catalog

The Astrophysical Journal Supplement Series
We present, for the first time, a systematic study of quasar-associated 2175 Å dust absorbers using spectroscopic data from the Sloan Digital Sky Survey Data Release 16 (DR16).

Exploring the Wolf Approach to Constraining NIR Extinction Laws in the Corona Australis Molecular Cloud

The Astronomical Journal
The viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep JHK _S photometry from the VISIONS survey, extinction maps with 1′ spatial

Searching for the Shortest-wavelength Aromatic Infrared Bands: No Evidence for the Predicted 1.05 μm Polycyclic Aromatic Hydrocarbon Feature

The Astrophysical Journal
Polycyclic aromatic hydrocarbons (PAHs) are responsible for a variety of near- and mid-infrared spectral features in Galactic and extragalactic sources.
