Extinction Distributions in Nearby Star-resolved Galaxies. I. M31
The Astronomical JournalAn extinction distribution of the Andromeda galaxy (M31) is constructed with member stars as tracers by fitting multiband photometric data from UKIRT/WFCAM, Panoramic Survey Telescope and Rapid Response System 1, and Gaia DR3.

Massive Acquisition of Ultraviolet Color Excess Information from GALEX and UVOT Bands
The Astrophysical Journal Supplement SeriesThis study employs stellar parameters from spectroscopic surveys and Zhang et al. (2023) based on Gaia BP/RP (XP) spectra, along with photometric data from Galaxy Evolution Explorer (GALEX), UV/Optical Telescope (UVOT), and Gaia, to obtain extensive ...

Dust in the small Magellanic cloud. 1: Interstellar polarization and extinction data [PDF]
, 1996 The typical extinction curve for the Small Magellanic Cloud (SMC), in contrast to that for the Galaxy, has no bump at 2175 A and has a steeper rise into the far ultraviolet.

Dust Absorption toward Supernova Remnant W44
The Astronomical JournalSupernova remnants (SNRs) can strongly affect the chemical composition of the interstellar dust. In this paper, we investigate to what degree the dust and ices are modified by observing four stars expected to be absorbed by a giant molecular cloud ...
