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 …

Polycyclic aromatic hydrocarbon (PAH) molecules are abundant and widespread throughout
the Universe, as revealed by their distinctive set of emission bands at 3.3, 6.2, 7.7, 8.6, 11.3 …

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 …

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

We present a simple, largely empirical but physically motivated model to interpret the mid-
and far-infrared spectral energy distributions of galaxies consistently with the emission at …

Molecular absorption and emission bands dominate the visible, infrared, and submillimeter
spectra of most objects with associated gas. These observations reveal a surprisingly rich …

The Planck and Herschel missions are currently measuring the far-infrared to millimeter
emission of dust, which combined with existing IR data, will for the first time provide the full …

Buckminsterfullerene (C60) was recently confirmed as the largest molecule identified in
space. However, it remains unclear how and where this molecule is formed. It is generally …

Dust is a ubiquitous feature of the cosmos, impinging directly or indirectly on most fields of
modern astronomy and astrophysics. Dust in the Galactic Environment, Second Edition …

We present maps tracing the fraction of dust in the form of polycyclic aromatic hydrocarbons
(PAHs) in IC 5332, NGC 628, NGC 1365, and NGC 7496 from JWST/MIRI observations. We …
