Laboratory infrared spectra and fragmentation chemistry of sulfur allotropes [PDF]
Sulfur is one of six life-essential elements, but its path from interstellar clouds to planets and their atmospheres is not well known. Astronomical observations in dense clouds have so far been able to trace only 1 percent of cosmic sulfur, in the form ...

Dust evolution, a global view: II. Top-down branching, nanoparticle fragmentation and the mystery of the diffuse interstellar band carriers [PDF]
The origin of the diffuse interstellar bands (DIBs), one of the longest-standing mysteries of the interstellar medium (ISM), is explored within the framework of The Heterogeneous dust Evolution Model for Interstellar Solids (THEMIS). The likely nature of

Synthesis and Spectroscopy of Buckminsterfullerene Cation
The assignment of several diffuse interstellar bands in the near-infrared to C60+ ions present at high abundance in space has renewed interest in the astrochemical importance of fullerenes and analogues.

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.

SEARCH FOR SPECTROSCOPIC FAMILIES AMONG DIFFUSE INTERSTELLAR BANDS
Diffuse interstellar bands (DIBs) await an explanation for many decades. One expects that significant progress in identification of DIBs’ carriers will be possible when all the known DIBs are divided into families in such a way that only one carrier is ...

Diffuse Interstellar Bands Toward HD 62542 [PDF]
Diffuse interstellar bands (DIBs) have been detected for the first time along the peculiar translucent line of sight toward HD 62542, which passes through a diffuse cloud core.

Evidence for the naphthalene cation in a region of the interstellar medium with anomalous microwave emission [PDF]
We report high resolution spectroscopy of the moderately reddened (A$_V$=3) early type star Cernis 52 located in a region of the Perseus molecular cloud complex with anomalous microwave emission.

Few anions exhibit electronically excited states, and, if they do, the one or two possible excitations typically transpire beyond the visible spectrum into the near-infrared.
