Diffuse interstellar clouds have long been thought to be relatively devoid of molecules,
because of their low densities and high radiation fields. However, in the past ten years or so …

Bimolecular reactions of phenyl-type radicals with the C4 and C5 hydrocarbons
vinylacetylene and (methyl-substituted) 1, 3-butadiene have been found to synthesize …

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

Polycyclic aromatic hydrocarbons (PAHs) are fundamental molecular building blocks of
fullerenes and carbonaceous nanostructures in the interstellar medium and in combustion …

Life is generally believed to emerge on Earth, to be at least functionally similar to life as we
know it today, and to be much simpler than modern life. Although minimal life is notoriously …

ABSTRACT Polycyclic Aromatic Hydrocarbons (PAHs) are carbon-based molecules
resulting from the union of aromatic rings and related species, which are likely responsible …

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 …

Mixtures of polycyclic aromatic hydrocarbons (PAHs) have been produced by means of laser
pyrolysis. The main fraction of the extracted PAHs was primarily medium-sized, up to a …

How complex carbonaceous molecules in space are, what their abundance is and on what
timescales they form are crucial questions within cosmochemistry. Despite the large …

Aims. Molecular hydrogen is the most abundant molecule in the Universe. It is thought that a
large portion of H 2 forms by association of hydrogen atoms to polycyclic aromatic …
