Modification of spectral properties of the PAH cations upon cluster formation
Astronomy & AstrophysicsContext. Polycyclic aromatic hydrocarbons (PAHs) and their clusters are widely invoked as carriers of unidentified infrared bands (UIBs) and are abundant in the interstellar medium (ISM).

A search for fine structure inside high resolution profiles of weak diffuse interstellar bands
, 2006 This paper presents a survey of the high-resolution profiles of selected, moderately weak diffuse interstellar bands (DIBs) between 4725 and 6730 Å. In very high signal-to-noise spectra, obtained as a result of averaging several individual exposures of

Extended correlations between diffuse interstellar bands [PDF]
The systematic analysis of the correlations between diffuse interstellar bands (DIBs) is extended to weak DIBs through the comprehensive catalogue of the Apache Peak Observatory (APO) of 559 DIBs in 25 lines of sight with diverse interstellar properties.

Probing the local bubble with diffuse interstellar bands. III. The northern hemisphere data and catalog [PDF]
, 2015 We present new high signal-to-noise ratio (S/N) observations of the diffuse interstellar bands (DIBs) in the Local Bubble and its surroundings. We observed 432 sightlines and obtain the equivalent widths of the ?5780 and ?5797 Å DIBs up to a distance of ~

Zagadnienia Filozoficzne w Nauce, 2017 In general introduction few examples of astronomical explanations of well-known and common local physical phenomena are presented. They are meant to show that it is often much easier to explain commonly experienced phenomena by investigating the behavior

Atacama Large Aperture Submillimeter Telescope (AtLAST) science: Our Galaxy
Open Research EuropeAs we learn more about the multi-scale interstellar medium (ISM) of our Galaxy, we develop a greater understanding for the complex relationships between the large-scale diffuse gas and dust in Giant Molecular Clouds (GMCs), how it moves,

Are aromatic hydrocarbons the carriers of the diffuse interstellar bands in the visible? [PDF]
, 1986 Large Polycyclic Aromatic Hydrocarbons (PAH) are the likely origin of the Unidentified Infrared Emission Feature. The molecules or their ions are also attractive candidates for the carriers of the Diffuse Interstellar Bands (DIBs) in the visible range ...

Are large organic molecules in comets similar to the Diffuse Interstellar Bands carriers?
, 2017 International audienceWe suggest that the refractory organic material found by COSIMA in 67P/CG comet dust (Fray et al., 2016) is made of aggregates of the same organic molecules which are present in the interstellar medium (ISM) and are producing in ...

Search for fullerenes and PAHs in the diffuse interstellar medium [PDF]
, 1995 . Recent studies suggest carbon-containing moleGuIes as the best candidates for carriers of the unidentified diffuse interstellar bands (DIBs), con-sidering their abundance and ability to form stable bonds in interstellar space. We have searched for new
