Investigating the interstellar dust through the Fe K-edge [PDF]
, 2017 Context. The chemical and physical properties of interstellar dust in the densest regions of the Galaxy are still not well understood. X-rays provide a powerful probe since they can penetrate gas and dust over a wide range of column densities (up to 1024

Thermal and non-thermal dust sputtering in hydrodynamical simulations of the multiphase interstellar medium [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We study the destruction of interstellar dust via sputtering in supernova (SN) shocks using three-dimensional hydrodynamical simulations. With a novel numerical framework, we follow both sputtering and dust dynamics governed by direct collisions, plasma ...

The nature of interstellar dust as revealed by light scattering
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011 Interstellar dust was first identified through the extinction that it causes of optical starlight. Initially, observational and theoretical studies of extinction were made to identify simple ways of removing the effect of extinction.

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 ...

X-ray Halos and Large Grains in the Diffuse Interstellar Medium [PDF]
, 2001 Recent observations with dust detectors on board the interplanetary spacecraft Ulysses and Galileo have recorded a substantial flux of large interstellar grains with radii between 0.25 and 2.0 mu entering the solar system from the local interstellar ...

Dust evolution in pre-stellar cores [PDF]
EPJ Web of Conferences, 2020 Dust grains are the building blocks of future planets. They evolve in size, shape and composition during the life cycle of the interstellar medium. We seek to understand the process which leads from diffuse medium grains to dust grains in the vicinity of

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.

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 ...

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.
