Thermodynamics of Giant Molecular Clouds: The Effects of Dust Grain Size

The Astrophysical Journal
The dust grain size distribution (GSD) likely varies significantly across star-forming environments in the Universe, but its impact on star formation remains unclear. This ambiguity arises because the GSD interacts nonlinearly with processes like heating,

Statistical properties of dust far-infrared emission

, 2007
The description of the statistical properties of dust emission gives important constraints on the physics of the interstellar medium but it is also a useful way to estimate the contamination of diffuse interstellar emission in the cases where it is ...

Imprints of the Local Bubble and Dust Complexity on Polarized Dust Emission

The Astrophysical Journal
Using 3D dust maps and Planck polarized dust emission data, we investigate the influence of the 3D geometry of the nearby interstellar medium (ISM) on the statistics of the dust polarization on large ( $80^{\prime} $ ) scales.

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.

A Power Spectral Study of PHANGS Galaxies with JWST MIRI: On the Spatial Scales of Dust and Polycyclic Aromatic Hydrocarbons

The Astrophysical Journal
The interstellar medium (ISM) consists of a diversity of structures across a range of spatial scales, intimately tied to galactic evolution. In this work, Fourier analysis is used to characterize the spatial structures of dust and polycyclic aromatic ...

Dust-extinction-curve Variation in the Translucent Interstellar Medium Is Driven by Polycyclic Aromatic Hydrocarbon Growth

The Astrophysical Journal Letters
The first all-sky, high-resolution, 3D map of the optical extinction curve of the Milky Way revealed an unexpected steepening of the extinction curve in the moderate-density, “translucent” interstellar medium (ISM).

Contactless Manipulation and Raman Analysis of Cometary Analogs and Micrometeorites by Acoustic Levitation

The Astrophysical Journal
Extraterrestrial material collected during space missions is highly exposed to contamination issues during on-Earth analysis. Although high-protection-level protocols were developed, to minimize the contamination due to sample manipulation and the ...
