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…

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…
