On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

On the Active Sites of Mg-bearing Interstellar Dust Grains: An Experimental and Theoretical Model Study of CO2 Activation

The Astrophysical Journal
Magnesium silicates represent an important component of interstellar dust. While the formation of molecules in the interstellar region is typically thought to take place in icy mantles covering such dust particles, the bare uncovered grains are hardly ...

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

The Near-infrared Extinction Law at High and Low Galactic Latitudes

The Astrophysical Journal
The Milky Way dust extinction curve in the near-infrared (NIR) follows a power-law form, but the value of the slope, β _NIR , is debated. Systematic variations in the slope of the Milky Way UV extinction curve are known to be correlated with variations ...

ALMA Reveals Diverse Dust-to-gas Mass Ratios and Quenching Modes in Old Quiescent Galaxies

The Astrophysical Journal Letters
Recent discoveries of dust and molecular gas in quiescent galaxies (QGs) up to z ∼ 4 challenge the long-standing view that the interstellar medium depletes rapidly once star formation ceases, raising key questions of whether dust and gas coevolve in QGs,

The binding energies of atoms on amorphous silicate dust: A computational study

Astronomy & Astrophysics
Context. We investigate the binding energies of atoms to interstellar dust particles, which play a key role in their growth and evolution as well as the chemical reactions on their surfaces. Aims.

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.

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 ...
