Tracing the Layers of Photodissociated Gas in the Trifid Nebula

The Astrophysical Journal
Photodissociated gas bears the signature of the dynamical evolution of the ambient interstellar medium impacted by the mechanical and radiative feedback from an expanding H ii region.

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 ABUNDANCE OF BORON IN DIFFUSE INTERSTELLAR CLOUDS [PDF]

The Astrophysical Journal, 2011
We present a comprehensive survey of boron abundances in diffuse interstellar clouds from observations made with the Space Telescope Imaging Spectrograph (STIS) of the Hubble Space Telescope. Our sample of 56 Galactic sight lines is the result of a complete search of archival STIS data for the B II 1362 resonance line, with each detection confirmed by ...

Evolution of prolate molecular clouds at HII boundaries - I. formation of fragment-core structures [PDF]

, 2014
The evolution of a prolate cloud at an HII boundary is investigated using smoothed particle hydrodynamics. The prolate molecular clouds in our investigation are setwith their semi-major axis perpendicular to the radiative direction of a plane-parallel ...

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.

What Rogue Hydrogen Clouds Tell Us about Galactic Magnetic Fields

The Astrophysical Journal
Observations 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.

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.

DESTRUCTION OF THE INTERSTELLAR CLOUDS BY THESHOCK WAVES

Odessa Astronomical Publications, 2008
We study the influence of the interstellar cloud structure irregularity on the dynamics of its destruction by a supernova shock wave. It is shown that irregular clouds are destroyed twice quickly as the spherical ones.
