Correlations between Dust Extinction Features across All Wavelength Scales: From Diffuse Interstellar Bands to R(V)
Andrew K. Saydjari, Gregory M. Green
Understanding variations in the dust extinction curve is imperative for using dust as a tracer of local structure in the interstellar medium, understanding dust chemistry, and obse…

The Dust Extinction Curve: Beyond R(V)
Gregory M. Green, Xiangyu Zhang, Ruoyi Zhang
The dust extinction curve is typically parameterized by a single variable, R(V), in optical and near-infrared wavelengths. R(V) controls the slope of the extinction-vs.-wavelength…

Dust extinction-curve variation in the translucent interstellar medium is driven by PAH growth
Xiangyu Zhang, Brandon S. Hensley, Gregory M. Green
The first all-sky, high-resolution, 3D map of the optical extinction curve of the Milky Way (Zhang & Green 2024) revealed an unexpected steepening of the extinction curve in the mo…
