iSELECTION: An Instrument to Study the Kinetics of Isomer‐Selected Gas‐Phase Ion‐Molecule Reactions

open access: yesChemistry–Methods, EarlyView.
Isomer‐specific reactivity is key in cluster chemistry. Herein, it is shown that how combining drift‐tube ion mobility with mass spectrometry enables the derivation of reaction rate coefficients for coexisting C40+$\text{C}_{40}^{+}$ isomers, opening new avenues for studying complex chemical systems ...

Theory of interstellar medium diagnostics [PDF]

open access: yes, 1983
The theoretical interpretation of observed interplanetary resonance luminescence patterns is used as one of the must promising methods to determine the state of the local interstellar medium (LISM).

Resolving the Interstellar Medium at the Peak of Cosmic Star Formation

open access: yes, 2018
The interstellar medium feeds both the formation of stars and the growth of black holes, making it a key ingredient in the evolution of galaxies.

Variability of GRB Afterglows Due to Interstellar Turbulence [PDF]

open access: yes, 1999
Gamma-Ray Burst (GRB) afterglows are commonly interpreted as synchrotron emission from a relativistic blast wave produced by a point explosion in an ambient medium, plausibly the interstellar medium of galaxies.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Electromagnetic Forces on a Relativistic Spacecraft in the Interstellar Medium [PDF]

open access: yes, 2017
A relativistic spacecraft of the type envisioned by the Breakthrough Starshot initiative will inevitably become charged through collisions with interstellar particles and UV photons.

Astrophysical Fractals: Interstellar Medium and Galaxies

open access: yes, 1999
The interstellar medium is structured as a hierachy of gas clouds, that looks self-similar over 6 orders of magnitude in scales and 9 in masses. This is one of the more extended fractal in the Universe.

Energy Landscapes in Chemical Reactions and Transport

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

SILICATE COMPOSITION OF THE INTERSTELLAR MEDIUM [PDF]

open access: yes, 2016
The composition of silicate dust in the diffuse interstellar medium and in protoplanetary disks around young stars informs our understanding of the processing and evolution of the dust grains leading up to planet formation.

Solid H2 in the interstellar medium

open access: yes, 2018
Condensation of H 2 in the interstellar medium (ISM) has long been seen as a possibility, either by deposition on dust grains or thanks to a phase transition combined with self-gravity.
