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

Recent observational and experimental evidence for the presence of complex organics in
space is reviewed. Remote astronomical observations have detected ∼∼ 200 gas-phased …

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 …

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 …

Buckminsterfullerene (C 60) has recently been detected through its infrared emission bands
in the interstellar medium (ISM), including in the proximity of massive stars, where physical …

We present a study of 16 planetary nebulae (PNe) where fullerenes have been detected in
their Spitzer Space Telescope spectra. This large sample of objects offers a unique …

ABSTRACT Fullerenes, including C60, C70, and C60+, are widespread in space through
their characteristic infrared vibrational features (C60+ also reveals its presence in the …

We suggest that the carrier of the unidentified infrared emission (UIE) bands is an
amorphous carbonaceous solid with mixed aromatic/aliphatic structures, rather than free …

In 2019 it was exactly 100 years ago that the first two DIBs, diffuse interstellar bands, were
discovered by Mary Lea Heger. Today some 500+ DIBs are known. In numerous …
