Scylla: Observational Evidence for an Order of Magnitude in Dust-mass Opacity Evolution with Interstellar Medium Density in the Large Magellanic Cloud

The Astrophysical Journal Letters
The emissivity of dust is known to vary greatly with radiative environment, density, grain chemistry, and geometry. Discrepancies between dust-mass surface densities derived from far-infrared (FIR) emission and visible extinction persist across and ...

Massive Acquisition of Ultraviolet Color Excess Information from GALEX and UVOT Bands

The Astrophysical Journal Supplement Series
This 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 ...

Supernova Remnants as a Probe of Dust Grains in the Interstellar Medium

, 2010
Interstellar dust grains play a crucial role in the evolution of the galactic interstellar medium (ISM). Despite its importance, however, dust remains poorly understood in terms of its origin, composition, and abundance throughout the universe. Supernova

Dust in a Hostile Environment: Interstellar Dust in the Line of Sight to HD62542 [PDF]

, 1996
HD 62542 is situated in a line of sight toward a ridge of dark matter in the Gum Nebula. That region is under the influence of UV radiation and stellar winds from hot stars. We use for the first time interstellar polarization and extinction data from the

Extinction Distributions in Nearby Star-resolved Galaxies. I. M31

The Astronomical Journal
An 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.

A Detailed Analysis of Intermediate-scale Structure in Optical Extinction Curves: Expanded Census and Two-family Classification

The Astrophysical Journal
The features of interstellar extinction curves serve as powerful diagnostics for interstellar dust, revealing information about its composition, size distribution, and the physical and chemical processes that shape it. D. Massa et al.

Interstellar extinction from photometric surveys: Application to four high-latitude areas

, 2020
© 2018 O. Malkov et al. Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from ...

Dust-extinction-curve Variation in the Translucent Interstellar Medium Is Driven by Polycyclic Aromatic Hydrocarbon Growth

The Astrophysical Journal Letters
The first all-sky, high-resolution, 3D map of the optical extinction curve of the Milky Way revealed an unexpected steepening of the extinction curve in the moderate-density, “translucent” interstellar medium (ISM).
