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…
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…
Unveiling the Milky Way dust extinction curve in 3D
Xiangyu Zhang, Gregory Green
Interstellar dust is a major foreground contaminant for many observations and a key component in the chemistry of the interstellar medium, yet its properties remain highly uncertai…
An Empirical Extinction Curve Revealed by Gaia XP Spectra and LAMOST
Ruoyi Zhang, Haibo Yuan, Bowen Huang +4
We present a direct measurement of extinction curves using corrected XP spectra of the common sources in DR3 and LAMOST DR7. Our analysis of approximately 370 thousan…
