ORGANIC DUST IN THE INTERSTELLAR MEDIUM [PDF]
Publications of The Korean Astronomical Society, 2014 The traditional view of dust in the interstellar medium is that it is made of graphite and silicates. In this paper, we discuss the evidence for complex organics being a major component of interstellar dust. Comparison between astronomical infrared spectra and laboratory spectra of amorphous carbonaceous materials suggests that organics of mixed ...

A Nest of Diffuse Interstellar Bands—Likely of Common Origin
The Astronomical JournalDiffuse 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 ...

, 2013 Many evolved stars travel through space at supersonic velocities, which leads to the formation of bow shocks ahead of the star where the stellar wind collides with the interstellar medium (ISM).

Clusters Stagnating During Condensation: Metastable Material or a Separate State of Matter?
Annalen der Physik, Volume 537, Issue 10, October 2025.Condensation stagnation, that is, the existence of a delay between nucleation and growth during the gas‐phase particle formation, is a crucial phenomenon, which manifests itself as the presence of supercritical clusters in resulting particulates. The light emission signature of stagnant clusters is identified in the magnesium particle flame in air, and,

The Astrophysical JournalThe chemistry within the interstellar medium (ISM) is notably influenced by the interplay between kinetics and photochemical processes, which play significant roles in both the formation and destruction of molecular species.

Effective Resistivity for Magnetohydrodynamic Simulation of Collisionless Magnetic Reconnection
Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.Abstract The electron inertia and the off‐diagonal electron pressure terms are well‐known for the frozen‐in condition breakdown in collisionless magnetic reconnection, which are naturally kinetic and difficult to employ in magnetohydrodynamic (MHD) simulations.

Plasma turbulence in the interstellar medium [PDF]
Plasma Physics and Controlled Fusion, 2019 The interstellar medium is a multi-phase, magnetized, and highly turbulent medium. In this paper, we address both theoretical and observational aspects of plasma turbulence in the interstellar medium. We successively consider radio wave propagation through a plasma and radio polarized emission.

Detection of the buckminsterfullerene cation (C60+) in space
, 2013 In the early 90s, C60+ was proposed as the carrier of two diffuse interstellar bands (DIBs) at 957.7 and 963.2 nm, but a firm identification still awaits gas-phase spectroscopic data.

Sleep and Dreams as Reflected by Science Fiction Literature and Films—Anything to Learn From?
Journal of Sleep Research, Volume 34, Issue 5, October 2025.ABSTRACT Sleep and dreams are frequent themes in science fiction (Sci‐Fi) literature and films, often used to explore questions about consciousness, reality, technology and the human experience. Sci‐Fi authors and filmmakers utilise the enigmatic nature of sleep and dreams to blur the boundaries between reality and imagination, raising philosophical ...

The presence of dust in the general interstellar medium is inferred from the extinction, polarization, and scattering of starlight; the presence of dark nebulae; interstellar depletions; the observed infrared emission around certain stars and various ...
