The End of the Road for Far-infrared Reddening Maps? Evidence for Reddening Errors Driven by Changes in Polycyclic Aromatic Hydrocarbon Abundance

The Astrophysical Journal
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 demonstrate that Galactic dust reddening maps constructed from observations ...

An Empirical Extinction Curve Revealed by Gaia XP Spectra and LAMOST

The Astrophysical Journal
We present a direct measurement of extinction curves using corrected Gaia XP spectra of the common sources in Gaia DR3 and LAMOST DR7. Our analysis of approximately 370,000 high-quality samples yielded a high-precision average extinction curve for the ...

The Spheroidal Analog Method for Modeling Irregular Porous Aggregates

The Astrophysical Journal
It is shown that the optical properties of an irregular porous grain with effective radius a _eff  ≲ 3 λ (where λ is the wavelength) can be well approximated by a “spheroidal analog”: a spheroid with appropriate axial ratio and size, with a dielectric ...
