All-sky three-dimensional dust density and extinction Maps of the Milky Way out to 2.8 kpc [PDF]

open access: yesMonthly notices of the Royal Astronomical Society
Three-dimensional dust density maps are crucial for understanding the structure of the interstellar medium of the Milky Way and the processes that shape it.

Detection of PAH Absorption and Determination of the Mid-infrared Diffuse Interstellar Extinction Curve from the Sight Line toward Cyg OB2-12 [PDF]

open access: yesAstrophysical Journal, 2020
The sight line toward the luminous blue hypergiant Cyg OB2-12 is widely used to study interstellar dust on account of its large extinction (AV ≃ 10 mag) and the fact that this extinction appears to be dominated by dust typical of the diffuse interstellar

Galaxies with grains: unraveling dust evolution and extinction curves with hydrodynamical simulations [PDF]

open access: yesAstronomy & Astrophysics
Dust in galaxies is an important tracer of galaxy properties and their evolution over time. The physical origin of the grain size distribution, the dust chemical composition, and, hence, the associated ultraviolet-to-optical extinctions in diverse ...

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

open access: yesOpen 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

Dust models post-Planck: constraining the far-infrared opacity of dust in the diffuse interstellar medium

open access: yes, 2015
We compare the performance of several dust models in reproducing the dust spectral energy distribution (SED) per unit extinction in the diffuse interstellar medium (ISM).

Three-dimensional maps of interstellar dust in the Local Arm: using Gaia, 2MASS, and APOGEE-DR14 [PDF]

open access: yesAstronomy & 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

The Interstellar Dust Properties of Nearby Galaxies [PDF]

open access: yesAnnual 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]

open access: yesAstrophysical Journal Supplement Series, 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.

Life Cycle of Dust in the Magellanic Clouds and the Milky Way

open access: yes, 2014
To a great extent, our understanding of the life cycle of dust is based on the observational and theoretical studies of the Milky Way and the Magellanic Clouds, which will be the topic of this contribution. Over past years, a large volume of observations

Infrared Emission from Interstellar Dust. IV. The Silicate-Graphite-PAH Model in the Post-Spitzer Era [PDF]

open access: yes, 2006
IR emission spectra are calculated for dust heated by starlight, for mixtures of amorphous silicate and graphitic grains, including varying amounts of PAH particles. The models are constrained to reproduce the average Milky Way extinction curve.
