Structure and Kinematics of Sh2-138—A Distant Hub-filament System in the Outer Galactic Plane
The Astrophysical Journal, 2023 We present a molecular line study of the Sh2-138 (IRAS 22308+5812) hub-filament system with the aim of investigating its structure and kinematics. Archival CO molecular line data from the Canadian Galactic Plane Survey (CO( J = 1–0)) for the wider region

Astronomy & Astrophysics, 2023 Context. Dusty magnetized structures observable in the far-infrared (FIR) at high Galactic latitudes are ubiquitous and found to be closely related to H I filaments with coherent velocity structures. Aims. Considering dimensionless morphological characteristics based on Minkowski functionals, we determine the distribution of filamentarities ℱ and ...

Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material
Meteoritics &Planetary Science, Volume 60, Issue 5, Page 1073-1094, May 2025.Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.

The Astrophysical JournalThe Herschel Gould Belt Survey showed that stars form in dense filaments in nearby molecular clouds. Recent studies suggest that massive filaments are bound by the slow shocks caused by accretion flows onto the filaments.

Magnetic Field of a Ring-like Molecular Cloud
The Astronomical JournalWe present a detailed study of the magnetic field structure in the G111 molecular cloud, a ring-like filamentary cloud within the NGC 7538 region. Our analysis combines multiwavelength polarization data and molecular-line observations to investigate the ...

The Multi-Phase Medium in the Interstellar Complex N44 [PDF]
, 1998 We have obtained high-resolution HI observations of N44, one of the largest HII complexes in the Large Magellanic Cloud. The distribution and internal motions of the HI gas show dynamic effects of fast stellar winds and supernova blasts.

Advances on the Links Between Turbulent and Submeso‐ to Mesoscales During EUREC4A
Earth and Space Science, Volume 12, Issue 2, February 2025.Abstract Turbulent processes in the atmospheric boundary layer (ABL) are parameterized in numerical weather prediction and climate models. Better understanding their modulation by larger‐scale organized structures, some of them being represented explicitly, is thus of great interest.

On the universality of interstellar filaments: theory meets simulations and observations [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 Filaments are ubiquitous in the universe. Recent observations have revealed that stars and star clusters form preferentially along dense filaments. Understanding the formation and properties of filaments is therefore a crucial step in understanding star formation.
