Magnetic reconnection detonation in supernova remnants

open access: yes, 2018
As a key process that refreshes the interstellar medium, the dynamics and radiative properties of the supernova remnant (SNR) expansion front not only reflect the physical environment of the old interstellar medium (ISM) surrounding the supernova, but ...

The Interstellar Medium In Galaxies Seen A Billion Years After The Big Bang [PDF]

open access: yes, 2015
Evolution in the measured rest frame ultraviolet spectral slope and ultraviolet to optical flux ratios indicate a rapid evolution in the dust obscuration of galaxies during the first 3 billion years of cosmic time (z>4).

Magnetic Fields in Giant Filaments Probed by the Velocity Gradient Technique: Regular Magnetic Field Interrupted by Magnetization Gaps

open access: yesThe Astrophysical Journal
We study the magnetic field structures in six giant filaments associated with the spiral arms of the Milky Way by applying the velocity gradient technique (VGT) to the ^13 CO spectroscopic data from the GRS, FUGIN, and SEDIGSM surveys.

Formation of molecular hydrogen on analogues of interstellar dust grains: experiments and modelling

open access: yes, 2005
Molecular hydrogen has an important role in the early stages of star formation as well as in the production of many other molecules that have been detected in the interstellar medium.

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.

Modelling dust processing and the evolution of grain sizes in the ISM using the method of moments

open access: yes, 2016
Interstellar dust grains do not have a single well-defined origin. Stars are demonstrably dust producers, but also efficient destroyers of cosmic dust. Dust destruction in the ISM is believed to be the result of SN shocks hitting the ambient ISM gas (and

Formation and destruction of polycyclic aromatic hydrocarbon clusters in the interstellar medium [PDF]

open access: yes, 2006
The competition between the formation and destruction of coronene clusters under interstellar conditions is investigated theoretically. The unimolecular nucleation of neutral clusters is simulated with an atomic model combining an explicit classical ...

Physical and Dynamical Conditions in Interstellar Clouds [PDF]

open access: yesSymposium - International Astronomical Union, 1980
The most far-reaching result to come from the study of interstellar molecules has been the recognition of a new class of galactic structures - molecular clouds. These clouds appear to contain most of the mass of the interstellar medium and are the objects from which new stars are formed.
