Polyacenes and diffuse interstellar bands [PDF]
The identification of the carriers of the diffuse interstellar bands (DIBs) remains to be established, with the exception of five bands attributed to C60+, although it is generally agreed that DIB carriers should be large carbon-based molecules (with ~10–100 atoms) in the gas phase, such as polycyclic aromatic hydrocarbons (PAHs), long carbon chains or

A Nest of Diffuse Interstellar Bands—Likely of Common Origin
Diffuse interstellar bands (DIBs) have been proposed to cluster into distinct “families” each potentially linked to a single carrier molecule. In our study, we focus on identifying such a family within the spectral range of approximately 4945–4990 Å ...

Probing the diffuse interstellar medium with diffuse interstellar bands [PDF]
This work investigates the small scale structure of the Diffuse Interstellar Medium. To do this optical spectroscopy is used to obtain spectra of early type stars which are used as background targets with which the Diffuse Interstellar Medium (ISM) is probed.

Putting the Diffuse Interstellar Bands on the Map – Literally! [PDF]
AbstractIn a quest to further our understanding of the diffuse interstellar medium (ISM) as well as the unidentified carriers of the diffuse interstellar bands (DIBs), we are mapping DIBs across the sky using hundreds of hot stars as background torches – globular clusters (in particular ω Centauri), nearby stars in and around the Local Bubble, and ...

Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes – diffuse interstellar bands connection [PDF]
We present high-resolution (R~15000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already been found. These spectra are of high-quality (S/N > 300) for PN Tc 1, which permits us to search for the expected electronic transitions of neutral C60 and diffuse interstellar bands (DIBs ...

Complex Organics in Space: A Changing View of the Cosmos
Planetary explorations have revealed that complex organics are widely present in the solar system. Astronomical infrared spectroscopic observations have discovered that complex organics are synthesized in large quantities in planetary nebulae and ...

A Comparison of the Simulations and Observations for a Nearby Spiral Arm
The analysis is focused on the ability of galactic open clusters to trace the spiral arms, based on the recent data releases from Gaia. For this, a simple 1D description of the motion of spiral arms and clusters is introduced.
