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.

Interstellar Filaments and the Statistics of Galactic H I [PDF]
, 1996 This paper presents a statistical explanation of filament formation in the Galactic atomic hydrogen. We claim that even in the absence of dynamical factors, the Gaussian field corresponding to the measured values of the spectrum of random density should ...

Geostandards and Geoanalytical Research, Volume 49, Issue 3, Page 495-533, September 2025.Key Points Synchrotron nano‐imaging is necessary to locate elemental nanophases. Trace metal quantification requires high sensitivity nano‐XRF. Trace metal speciation relies on nano‐XANES using nano‐XRF. This chapter (Nano‐Imaging for Advanced X‐ray Fluorescence and Absorption Spectroscopy Applications) is a contribution to the Geostandards and ...

On the Formation of Density Filaments in the Turbulent Interstellar Medium [PDF]
, 2019 This study is motivated by recent observations of ubiquitous interstellar density filaments and guided by modern theories of compressible magnetohydrodynamic (MHD) turbulence. The interstellar turbulence shapes the observed density structures.

H i Self-absorption toward the Cygnus X North: From Atomic Filament to Molecular Filament
The Astrophysical Journal Letters, 2023 Using the H i self-absorption data from the Five-hundred-meter Aperture Spherical radio Telescope, we perform a study of the cold atomic gas in the Cygnus X North region.

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.

When Magnetic Fields Sculpt the Sky: The Riegel–Crutcher Cloud in Optical Polarization
The Astrophysical JournalFilamentary structures are ubiquitous in the interstellar medium, yet the extent to which magnetic fields influence the morphology of cold atomic gas remains an open question.

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.

Physik in unserer Zeit, Volume 56, Issue 1, Page 30-37, January 2025.Galaxien wie die Milchstraße sind umhüllt von einem gigantischen Kokon aus diffusem Gas. Aktuelle Forschungsergebnisse belegen, dass dieses zirkumgalakische Medium eine entscheidende Rolle für die Entstehung und Entwicklung von Galaxien spielt. Zusammenfassung Als zirkumgalaktisches Medium bezeichnet man die gasförmigen Hüllen von Galaxien, die sich ...
