Molecular hydrogen is the most abundant molecule in the universe. It is the first one to form
and survive photo-dissociation in tenuous environments. Its formation involves catalytic …

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 …

We introduce the thesan project, a suite of large volume () radiation-magnetohydrodynamic
simulations that simultaneously model the large-scale statistical properties of the …

We present a new model of interstellar dust in which large grains are a single composite
material," astrodust," and nanoparticle-sized grains come in distinct varieties including …

Aims. We analyze the applicability of far-infrared fine-structure lines [Cii] 158 μm,[Oi] 63 μm,
and [Oiii] 88 μm to reliably trace the star formation rate (SFR) in a sample of low-metallicity …

Large polycyclic aromatic hydrocarbon (PAH) molecules carry the infrared (IR) emission
features that dominate the spectra of most galactic and extragalactic sources. This review …

Aims. The goal of this paper is to analyse the behaviour of the gas-to-dust mass ratio (G/D)
of local Universe galaxies over a wide metallicity range. We especially focus on the low …

Context. The evolution of amorphous hydrocarbon materials, aC (: H), principally resulting
from ultraviolet (UV) photon absorption-induced processing, are likely at the heart of the …

During the commissioning of JWST, the medium-resolution spectrometer (MRS) on the mid-
infrared instrument (MIRI) observed the planetary nebula SMP LMC 058 in the Large …

This work provides a comprehensive overview of our theoretical and observational
understanding of the interstellar medium of galaxies. With emphasis on the microscopic …
