On the Spatial Distribution of 13CO Structures within 12CO Molecular Clouds
The Astrophysical Journal, 2023 We look into the 2851 ^12 CO molecular clouds harboring ^13 CO structures to reveal the distribution of the projected angular separations and radial velocity separations between their internal ^13 CO structures.

Photoabsorption and photodissociation of molecules important in the interstellar medium [PDF]
The photo absorption, photo dissociation, and fluorescence cross sections of interstellar molecules and radicals were measured in the vacuum ultraviolet region. These quantitative optical data are useful for understanding of the formation and destruction

Revisiting CN<sup>-</sup> Formation Mechanisms in Electron Collisions with Benzonitrile. [PDF]
ChemphyschemThis study explores negative ion formation via electron attachment, revealing CN− formation at 3.0 and 7–10 eV. Dissociation pathways are analyzed using G4(MP2) and CASPT2 calculations, highlighting the coupling between the π4* and σ* resonances critical for interstellar chemistry. Radiation‐induced processes in the aromatic cyano compound benzonitrile

Dust evolution, a global view: II. Top-down branching, nanoparticle fragmentation and the mystery of the diffuse interstellar band carriers [PDF]
Royal Society Open Science, 2016 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

The efficiency of photodissociation for molecules in interstellar ices [PDF]
, 2018 Processing by interstellar photons affects the composition of the icy mantles on interstellar grains. The rate of photodissociation in solids differs from that of molecules in the gas phase. The aim of this work was to determine an average, general ratio

Broadband VLA Spectral-line Survey of a Sample of Ionized Jet Candidates
The Astrophysical Journal Supplement Series, 2023 The study of the interaction between ionized jets, molecular outflows, and their environments is critical to understanding high-mass star formation, especially because jets and outflows are thought to be key in the transfer of angular momentum outward ...

Extraterrestrial prebiotic molecules: photochemistry vs. radiation chemistry of interstellar ices.
Chemical Society Reviews, 2019 In 2016, unambiguous evidence for the presence of the amino acid glycine, an important prebiotic molecule, was deduced based on in situ mass-spectral studies of the coma surrounding cometary ice.
