Dust in the diffuse interstellar medium: Extinction, emission, linear and circular polarisation [PDF]
, 2013 We present a model for the diffuse interstellar dust that explains the observed wavelength-dependence of extinction, emission, and the linear and circular polarisation of light. The model is set up with a small number of parameters.

The Dust Extinction Curve: Beyond R(V)
The Astrophysical JournalThe dust extinction curve is typically parameterized by a single variable, R ( V ), in optical and near-infrared wavelengths. R ( V ) controls the slope of the extinction-versus-wavelength curve, and is thought to reflect the grain-size distribution and ...

Updated Gaia-2MASS 3D maps of Galactic interstellar dust [PDF]
Astronomy & Astrophysics, 2022 Three-dimensional (3D) maps of Galactic interstellar dust are a tool for a wide range of uses. We aim to construct 3D maps of dust extinction in the Local Arm and surrounding regions.

Oxygen and iron in interstellar dust: An X-ray investigation [PDF]
Astronomy & Astrophysics, 2022 Understanding the chemistry of the interstellar medium (ISM) is fundamental for the comprehension of the Galactic and stellar evolution. X-rays provide an excellent way to study the dust chemical composition and crystallinity along different sight-lines ...

Variations of Interstellar Gas-to-dust Ratios at High Galactic Latitudes [PDF]
Astrophysical Journal, 2023 Interstellar dust at high Galactic latitudes can influence astronomical foreground subtraction, produce diffuse scattered light, and soften the UV spectra of quasars.

SpeX Near-infrared Spectroscopic Extinction Curves in the Milky Way
The Astrophysical Journal, 2022 Interstellar dust extinction curves provide valuable information about dust properties, including the composition and size of the dust grains, and are essential to correct observations for the effects of interstellar dust.

An R V Map of the Milky Way Revealed by LAMOST
The Astrophysical Journal Supplement Series, 2023 The total-to-selective extinction ratio, R _V , is a key parameter for tracing the properties of interstellar dust, as it directly determines the variation of the extinction curve with wavelength.
