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

A critical review of the very long-standing problem of the diffuse interstellar bands is
presented with emphasis on spectroscopic aspects of observational, modelling and …

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 …

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 …

The carriers of the diffuse interstellar bands (DIBs) are largely unidentified molecules
ubiquitously present in the interstellar medium (ISM). After decades of study, two strong and …

In a sample of 114 diffuse cloud sightlines spanning a wide range of interstellar
environments, we find the equivalent widths of the diffuse interstellar bands (DIBs) λ6196. 0 …

Context. The Tarantula Nebula (aka 30 Dor) is a spectacular star-forming region in the Large
Magellanic Cloud (LMC), seen through gas in the Galactic disc and halo. Diffuse interstellar …

The Large Magellanic Cloud (LMC) offers a unique laboratory to study the diffuse interstellar
bands (DIBs) under conditions that are profoundly different from those in the Galaxy. DIB …

The identification of the carriers of the diffuse interstellar bands (DIBs) remains to be
established, with the exception of five bands attributed to C, although it is generally agreed …
