An All-sky 3D Dust Map Based on Gaia and LAMOST

The Astrophysical Journal Supplement Series
We present a comprehensive 3D dust-reddening map covering the entire Milky Way, constructed by combining reddening estimates based on Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST) low-resolution spectra ( E ( B  −  V ) _LAMOST ) with ...

A First Taste of MEAD (Measuring Extinction and Abundances of Dust). I. Diffuse Milky Way Interstellar Dust Extinction Features in JWST Infrared Spectra

The Astronomical Journal
We present the initial results of the Measuring Extinction and Abundances of Dust project, with a focus on the dust extinction features observed in our JWST near- and mid-infrared spectra of nine diffuse Milky Way sightlines (1.2 ≤ A ( V ) ≤ 2.5).

Modeling the Optical Colors of Galactic Cirrus Clouds in the Stripe 82 Region

The Astronomical Journal
Observations have shown that the optical colors of Galactic cirrus clouds differ significantly from those of extragalactic sources; thus, they can be used to distinguish Galactic cirrus from extragalactic low surface brightness (LSB) features.

Analysis of "Midnight" Tracks in the Stardust Interstellar Dust Collector: Possible Discovery of a Contemporary Interstellar Dust Grain

, 2010
In January 2006, the Stardust sample return capsule returned to Earth bearing the first solid samples from a primitive solar system body, Comet 81P/Wild2, and a collector dedicated to the capture and return of contemporary interstellar dust.

Extinction Distributions in Nearby Star-resolved Galaxies. II. M33

The Astronomical Journal
Extinction maps are essential for tracing interstellar dust and enabling accurate stellar population studies in galaxies. Here, a high-resolution extinction distribution of the nearby Triangulum galaxy (M33), is constructed by fitting multiband color ...

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 ...

Dust destruction in interstellar shocks

, 2003
Ein Teil der interstellaren Materie (ISM) liegt in Form von winzigen Festkörpern vor, die mit dem interstellaren Gas vermischt sind. Diese Teilchen werden als interstellarer Staub bezeichnet.

Interstellar dust as generator of x ray radiation

, 1989
The x ray generation due to arising of hot dense plasma balls at high-velocity (greater than or equal to 70 km/s) collisions of dust grains in the interstellar medium is considered.
