Interstellar processes: Ortho/para conversion, radiative association, and dissociative recombination
EPJ Web of Conferences, 2015 The study of the ortho-to-para ratio of assorted gas-phase interstellar molecules such as H2, H2O, NH3, and H2O+ has gained interest in recent years, based partially on new spectral observations of light hydrides by the Herschel Space Observatory ...

Frontiers in Astronomy and Space Sciences, 2023 Combined in situ observations of the interstellar wind through the solar system and of its pickup ions (PUIs), implanted after ionization in the solar wind, explain, in comparison with interstellar absorption lines of nearby stars, that the Sun is in an ...

Cloud-to-cloud Velocity Dispersions Across a Local Arm Segment
The Astrophysical JournalUsing a large sample of 9617 molecular clouds (MCs) from the Milky Way Imaging Scroll Painting survey, we mainly measure one-dimensional cloud-to-cloud velocity dispersions across a 450 deg ^2 segment of the Local Arm in the Galactic second quadrant.

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, EarlyView.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 ...

Interstellar Scintillation and Clouds of the Interstellar Turbulent Plasma [PDF]
International Astronomical Union Colloquium, 2001 AbstractData on interstellar diffraction and refraction scintillation of pulsars are analyzed. Comparison between theory and the observational data shows that two types of spectra for electron density fluctuations are realized in the interstellar medium: pure power law and piecewise with a break. The distribution of turbulent plasma in the Galaxy has a

Tidal Disruption of “Snow Clouds” by Unassociated Stars
The Astrophysical JournalIt has been suggested that star-forming galaxies may host a substantial, dark reservoir of gas in the form of planetary-mass molecular clouds that are so cold that H _2 can condense.

Journal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.New calculations have been applied to the pyrolysis of pyrrole under shock‐tube conditions and to the radical‐radical reaction between allyl and •CN at low temperature and pressure, using the same mechanistic scheme for both. ABSTRACT The pyrolysis of pyrrole has previously been studied in shock‐tube experiments and in jet‐stirred reactors. The results

Kinematics of H I Envelopes Associated with Molecular Clouds
The Astronomical JournalWe investigate the evolution of molecular clouds through the kinematics of their atomic hydrogen (H I ) envelopes, using ^12 CO and 21 cm emission to trace the molecular and atomic gas, respectively.

FORMATION OF SMALL-SCALE STRUCTURES IN THEINTERSTELLAR MEDIUM
Odessa Astronomical Publications, 2008 We consider formation of small scale structures in the process of interstellar cloud destruction by shock waves. We calculate statistical properties of HI column densities, optical depth and brightness temperature in 21 cm line.
