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 …

In this chapter we will discuss the evolution of dust in protoplanetary disks, focusing on the
processes of grain growth and the observational consequences of this process. In the …

Most of the celestial γ rays detected by the Large Area Telescope (LAT) on board the Fermi
Gamma-ray Space Telescope originate from the interstellar medium when energetic cosmic …

This paper presents an all-sky model of dust emission from the Planck 353, 545, and 857
GHz, and IRAS 100 μm data. Using a modified blackbody fit to the data we present all-sky …

The James Webb Space Telescope (JWST, Gardner et al. 2006) is a 6.5 m space telescope
launched in 2021 December and is developed by the National Aeronautics and Space …

Here we introduce the interstellar dust modelling framework THEMIS (The Heterogeneous
dust Evolution Model for Interstellar Solids), which takes a global view of dust and its …

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 …

We estimate the conversion factor relating CO emission to H 2 mass, α CO, in five Local
Group galaxies that span approximately an order of magnitude in metallicity—M 31, M 33 …

Cold dark clouds are nearby members of the densest and coldest phase in the Galactic
interstellar medium, and represent the most accessible sites where stars like our Sun are …

Hi-GAL, the Herschel infrared Galactic Plane Survey, is an Open Time Key Project of the
Herschel Space Observatory. It will make an unbiased photometric survey of the inner …
