Masses of interstellar gas clouds
, 1983 The equilibrium masses of the interstellar gas clouds have been calculated when the clouds are imbedded with magnetic fields. It is found that the masses of these clouds may be of the order of several thousand solar masses.

The Determination of Electron Abundances in Interstellar Clouds [PDF]
Symposium - International Astronomical Union, 1979 A new method for estimating electron fractions in shielded molecular clouds is proposed on the basis of gas phase ion-molecule reactions which involves measuring the quantity . Applied to existing data, it yields upper limits to Xe in the range from 10−8 to 10−7 for a variety of clouds, warm as well as cool.

The Role of Benzonitrile Chlorination Explored by Dissociative Electron Attachment
ChemPhysChem, Volume 27, Issue 9, 14 May 2026.Experimental and theoretical dissociative electron attachment study of 2‐ and 4‐chlorobenzonitrile. The dissociative electron attachment process to ortho‐ and para‐chlorobenzonitrile was investigated in the 0–12 eV energy range with a crossed‐beam time‐of‐flight mass spectrometer, supported by quantum chemical scattering calculations.

Structure and Spectroscopy of Criegee Intermediates in Gas‐ and Aqueous Environments
Helvetica Chimica Acta, Volume 109, Issue 5, May 2026.ABSTRACT The dynamics and spectroscopy of the small (H2COO) and large (CH3CHOO) Criegee intermediates (CIs) in the gas phase, inside/on water droplets, on amorphous solid water (ASW) and in bulk water are investigated using validated energy functions.

Modeling sulfur depletion in interstellar clouds [PDF]
Astronomy & Astrophysics, 2019 Context. The elemental depletion of interstellar sulfur from the gas phase has been a recurring challenge for astrochemical models. Observations show that sulfur remains relatively non-depleted with respect to its cosmic value throughout the diffuse and translucent stages of an interstellar molecular cloud, but its atomic and molecular gas-phase ...

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

What Rogue Hydrogen Clouds Tell Us about Galactic Magnetic Fields
The Astrophysical JournalObservations of the Milky Way and external galaxies support the idea that large-scale magnetic fields are concentrated in galactic disks, with halo magnetic fields at least an order of magnitude weaker.
