The Near-infrared Extinction Law at High and Low Galactic Latitudes

The Astrophysical Journal
The Milky Way dust extinction curve in the near-infrared (NIR) follows a power-law form, but the value of the slope, β _NIR , is debated. Systematic variations in the slope of the Milky Way UV extinction curve are known to be correlated with variations ...

The binding energies of atoms on amorphous silicate dust: A computational study

Astronomy & Astrophysics
Context. We investigate the binding energies of atoms to interstellar dust particles, which play a key role in their growth and evolution as well as the chemical reactions on their surfaces. Aims.

ALMA Reveals Diverse Dust-to-gas Mass Ratios and Quenching Modes in Old Quiescent Galaxies

The Astrophysical Journal Letters
Recent discoveries of dust and molecular gas in quiescent galaxies (QGs) up to z ∼ 4 challenge the long-standing view that the interstellar medium depletes rapidly once star formation ceases, raising key questions of whether dust and gas coevolve in QGs,

Supernova Remnants as a Probe of Dust Grains in the Interstellar Medium

, 2010
Interstellar dust grains play a crucial role in the evolution of the galactic interstellar medium (ISM). Despite its importance, however, dust remains poorly understood in terms of its origin, composition, and abundance throughout the universe. Supernova

Interstellar dust : a new field of application for physical chemistry

, 1994
The purpose of this paper is to draw the attention on the needs of astronomy in chemical physics expertise. Interstellar dust is a case in point. After summarizing briefly the state of knowledge in this field, we describe four "hot" issues, currently ...

Thermally Irreversible Sulfur Chemisorption on Silicate Grains as a Major Sulfur Reservoir in Molecular Clouds

The Astrophysical Journal
Sulfur (S) chemistry in the interstellar medium remains poorly constrained due to the long-standing “missing sulfur” problem, where a significant fraction of cosmic sulfur in molecular clouds remains unidentified. To gain a comprehensive understanding of

The Journey of Interstellar Dust

, 2007
Interstellar dust particles undergo a complex journey in space. It commences with their formation in stellar outflows or outbursts, but may end in very different ways. Their fates range from sudden "death by destruction" promptly after their formation to
