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 ...

Dust evolution, a global view: II. Top-down branching, nanoparticle fragmentation and the mystery of the diffuse interstellar band carriers [PDF]
Royal Society Open Science, 2016 The origin of the diffuse interstellar bands (DIBs), one of the longest-standing mysteries of the interstellar medium (ISM), is explored within the framework of The Heterogeneous dust Evolution Model for Interstellar Solids (THEMIS). The likely nature of

Chemical Kinetics Simulations of Ice Chemistry on Porous Versus Non-Porous Dust Grains
Frontiers in Astronomy and Space Sciences, 2021 The degree of porosity in interstellar dust-grain material is poorly defined, although recent work has suggested that the grains could be highly porous.

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.

Heliospheric modulation of the interstellar dust flow on to Earth [PDF]
Astronomy & Astrophysics, 2018 Aims. Based on measurements by the Ulysses spacecraft and high-resolution modelling of the motion of interstellar dust (ISD) through the heliosphere we predict the ISD flow in the inner planetary system and on to the Earth.

Prediction of the In-Situ Dust Measurements of the Stardust Mission to Comet 81P/Wild 2 [PDF]
, 1999 We predict the amount of cometary, interplanetary, and interstellar cosmic dust that is to be measured by the Cometary and Interstellar Dust Analyzer (CIDA) and the aerogel collector on-board the Stardust spacecraft during its fly-by of comet P/Wild 2 ...

Interstellar dust within the life cycle of the interstellar medium
EPJ Web of Conferences, 2012 Cosmic dust is omnipresent in the Universe. Its presence influences the evolution of the astronomical objects which in turn modify its physical and chemical properties.

Odessa Astronomical Publications, 2020 Cosmic-ray induced γ-ray emission in active galactic nuclei (AGN) has been examined in this study for the first time. Cross-sections for the formation of γ-quanta in such cosmic-ray collisions were selected in the 1-150 MeV energy range.

Modeling the Motion and Distribution of Interstellar Dust inside the Heliosphere [PDF]
, 1999 The interaction of dust grains originating from the local interstellar cloud with the environment inside the heliosphere is investigated. As a consequence of this interaction the spatial distribution of interstellar dust grains changes with time.
