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 …

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

Context. Various studies have emphasised variations in the charge state and composition of
the interstellar polycyclic aromatic hydrocarbon (PAH) population in photodissociation …

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 …

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

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 …

A family of unidentified infrared emission (UIE) bands has been observed throughout the
Universe. The current observed spectral properties of the UIE bands are summarized. These …

Aims. We study the effects of local environmental conditions affecting the diffuse interstellar
band (DIB) carriers within the Upper Scorpius subgroup of the Sco OB2 association. The aim …

Inter-and circumstellar ices comprise different molecules accreted on cold dust particles.
These icy dust grains provide a molecule reservoir where particles can interact and react. As …
