Dust evolution across cosmic times as seen through DUSTY-GAEA

Astronomy & Astrophysics
For many decades, dust has been recognised as an important ingredient in galaxy formation and evolution. This paper presents a novel self-consistent implementation of dust formation by stars, destruction by supernova shocks and hot gas, and growth within

Dust Evolution in Simulated Multiphase Galactic Outflows

The Astrophysical Journal
We present the first large-scale, high-resolution simulations of dusty, star formation feedback-driven galactic outflows. Using the Cholla hydrodynamics code, we investigate dust sputtering in these environments for grains ranging in size from 1 to 0.001

Mechanical Properties of Dust, Pebbles, and Planetesimals Based on Johnson–Kendall–Roberts, Griffith, and Weibull Theories

The Astrophysical Journal
Mechanical properties of small bodies such as dust, pebbles, and planetesimals are key to better understanding the formation of planetary systems against their collisional destruction.

Tensile Strength of Dust, Pebbles, and Planetesimals: A Simple Mathematical Formula from Aggregates to Monoliths Based on an Extension of an Elastic Theory for Particle Assemblies to Molecular Networks

The Astrophysical Journal
The tensile strength of solid particles is the key parameter that controls not only the formation of planetesimals in protoplanetary disks but also outburst and splitting of comets and rotational bursting of asteroids in planetary systems.

Strong Near-infrared Emission Following the Long-duration GRB 211211A: Dust Heating as an Alternative to a Kilonova

The Astrophysical Journal
The prolonged near-infrared (NIR) emission observed following the long-duration GRB 211211A is inconsistent with afterglow emission from the shock being driven into the circumstellar medium (CSM) as well as with emission from a possible underlying ...

An Increase in the Prevalence of Ionized Outflows in Galaxies with Coronal Line Emission: Feedback in Action?

The Astrophysical Journal
Coronal lines (CLs), which arise from collisionally excited forbidden transitions from highly ionized species, are a powerful diagnostic tool in uncovering active galactic nuclei (AGNs) and constraining their properties.

Mechanical Torque Disruption of Dust Grains Induced by Supernova Shock Waves

The Astrophysical Journal
The feedback from massive stars drives the evolution of interstellar dust grains by altering their physical properties via a number of radiative and mechanical processes.

Dusty Common Envelope Evolution

Galaxies
We present the first hydrodynamical simulations of common envelope evolution that include the formation of dust and the effect of radiation pressure on dust grains.

New Neutral–Neutral Pathways in the Chemistry of Silicon- and Sulfur-bearing Molecules in the Cold Interstellar Medium

The Astrophysical Journal
Silicon is the most abundant third-row element in space and plays a major role in interstellar dust as silicate particles. Furthermore, silicon is important for the formation of silicate dust in oxygen-rich AGB stars and in supernova remnants.

Destruction of the interstellar dust by a supernova

Destruction of the interstellar dust proceeds primary behind supernova shocks. The previous estimates of the mass of the interstellar dust destroyed in the SN remnant do not take into account the physical properties of the ambient medium. Here we consider how some parameters, i.e.
