Mapping Dust Attenuation and the 2175 Å Bump at Kiloparsec Scales in Nearby Galaxies
The Astrophysical Journal, 2023 We develop a novel approach to measure the dust attenuation properties of galaxies, including the dust opacity, the shape of the attenuation curve, and the strength of the 2175 Å absorption feature.

Dust absorption and scattering in the silicon K-edge [PDF]
, 2019 The composition and properties of interstellar silicate dust are not well understood. In X-rays, interstellar dust can be studied in detail by making use of the fine structure features in the Si K-edge.

Interstellar dust in galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1990 Current ideas about the nature of interstellar dust in galaxies are reviewed, with a strong emphasis on the nature of the very small grain component needed to explain the mid-infrared diffuse emission and unidentified infrared features. Models for the infrared spectra of galaxies are reviewed and the evidence that most of the radiation in star-forming ...

The Power of the Rings: The GRB 221009A Soft X-Ray Emission from Its Dust-scattering Halo
The Astrophysical Journal Letters, 2023 GRB 221009A is the brightest gamma-ray burst (GRB) ever detected that has occurred at low Galactic latitude. Owing to this exceptional combination, its prompt X-ray emission could be detected for weeks in the form of expanding X-ray rings produced by ...

Properties of interstellar wind leading to shape morphology of the dust surrounding HD 61005
, 2017 A structure formed by dust particles ejected from the debris ring around HD 61005 is observed in the scattered light. The main aim here is to constrain interstellar wind parameters that lead to shape morphology in the vicinity of HD 61005 using currently

Aliphatic hydrocarbon content of interstellar dust [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 In the interstellar medium, carbon is distributed between the gas and solid phases. However, while about half of the expected carbon abundance can be accounted for in the gas phase, there is considerable uncertainty as to the amount incorporated in interstellar dust.
