Gaia-2MASS 3D maps of Galactic interstellar dust within 3 kpc [PDF]
Astronomy & Astrophysics, 2019 Gaia stellar measurements are currently revolutionizing our knowledge of the evolutionary history of the Milky Way. 3D maps of the interstellar dust provide complementary information and are a tool for a wide range of uses.

Diffuse interstellar bands as dust indicators: The contribution from 3D maps [PDF]
Astronomy & AstrophysicsThree-dimensional (3D) distributions of the 862 nm diffuse interstellar band (DIB) carrier have been computed based on Gaia parallaxes and DIB catalogues, in parallel with 3D maps of dust extinction density.

INTERSTELLAR DUST GRAINS [PDF]
, 2003 ▪ Abstract This review surveys the observed properties of interstellar dust grains: the wavelength-dependent extinction of starlight, including absorption features, from UV to infrared; optical luminescence; infrared emission; microwave emission; optical,

Three-dimensional maps of interstellar dust in the Local Arm: using Gaia, 2MASS, and APOGEE-DR14 [PDF]
Astronomy & Astrophysics, 2018 Context. Gaia data and stellar surveys open the way to the construction of detailed 3D maps of the Galactic interstellar (IS) dust based on the synthesis of star distances and extinctions. Dust maps are tools of broad use, also for Gaia-related Milky Way

Interstellar extinction from photometric surveys: application to four high-latitude areas
Open Astronomy, 2018 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 various surveys. It yields a

CMB Shadows: The Effect of Interstellar Extinction on Cosmic Microwave Background Polarization and Temperature Anisotropy [PDF]
Astrophysical Journal, 2020 We evaluate the degradation of the accuracy of the component separation between the cosmic microwave background (CMB) and foreground components caused by neglect of absorption of the CMB’s monopole component by the galactic interstellar matter.

A Dynamical Constraint on Interstellar Dust Models from Radiative Torque Disruption [PDF]
Astrophysical Journal, 2018 Interstellar dust is an essential component of the interstellar medium (ISM) and plays critical roles in astrophysics. Achieving an accurate model of interstellar dust is therefore of great importance.

The Near-infrared Extinction Law at High and Low Galactic Latitudes
The Astrophysical JournalThe Milky Way dust extinction curve in the near-infrared (NIR) follows a power-law form, but the value of the slope, β _NIR , is debated. Systematic variations in the slope of the Milky Way UV extinction curve are known to be correlated with variations ...

The Interstellar Dust Properties of Nearby Galaxies [PDF]
Annual Review of Astronomy and Astrophysics, 2017 This article gives an overview of the constitution, physical conditions, and observables of dust in the interstellar medium of nearby galaxies. We first review the macroscopic, spatial distribution of dust in these objects and its consequences for our ...

Interstellar Extinction and Elemental Abundances [PDF]
, 2020 Elements in the interstellar medium (ISM) exist in the form of gas or dust. The interstellar extinction and elemental abundances provide crucial constraints on the composition, size, and quantity of interstellar dust.
