Astrochemistry lies at the nexus of astronomy, chemistry, and molecular physics. On the
basis of precise laboratory data, a rich collection of more than 200 familiar and exotic …

Conspectus Polycyclic aromatic hydrocarbon molecules (PAHs) are ubiquitously present at
high abundances in the Universe. They are detected through their infrared (IR) fluorescence …

Fullerenes have recently been detected in various circumstellar and interstellar
environments, raising the question of their formation pathway. It has been proposed that they …

This roadmap article highlights recent advances, challenges and future prospects in studies
of the dynamics of molecules and clusters in the gas phase. It comprises nineteen …

Context. Mid-infrared observations of photodissociation regions (PDRs) are dominated by
strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs are …

This review is concerned with the formation of molecules in the interstellar medium (ISM),
which is composed mainly of regions of gas and dust known as interstellar clouds, ranging …

Recently, the presence of fullerenes in the interstellar medium (ISM) has been confirmed
and new findings suggest that these fullerenes may possibly form from polycyclic aromatic …

Polycyclic aromatic hydrocarbons (PAHs) are abundant in many regions of the Universe,
representing a major reservoir for cosmic carbon. However, their formation pathways in cold …

Laboratory studies play a crucial role in understanding the chemical nature of the interstellar
medium (ISM), but the disconnect between experimental timescales and the timescales of …

Context. NGC 7023 is a well-studied reflection nebula, which shows strong emission from
polycyclic aromatic hydrocarbon (PAH) molecules in the form of aromatic infrared bands …
