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 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 …

The review contains an analysis of the observed and model curves of the interstellar
extinction and polarization. The observations mainly give information on dust in diffuse and …

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 report the clear detection of the 2175 Å dust absorption feature in the optical afterglow
spectrum of the gamma-ray burst (GRB) GRB 070802 at a redshift of z= 2.45. This is the …

Studies of extinction curves provide insights into the properties of interstellar dust. Until
recently, however, very few extinction curves existed outside the local group. GRB …

The exact nature of the 2175 extinction bump, the strongest spectroscopic absorption feature
superimposed on the interstellar extinction curve, remains unknown ever since its discovery …

Interstellar polycyclic aromatic hydrocarbons (PAHs) are strongly affected by the absorption
of vacuum ultraviolet (VUV) photons in the interstellar medium (ISM), yet the branching ratio …

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 …

Machine learning feature importance calculations are used to determine the molecular
substructures that are responsible for mid-and far-infrared (IR) emission features of neutral …
