Magnetic Misalignment of Interstellar Dust Filaments [PDF]
The Astrophysical Journal, 2023 We present evidence for scale-independent misalignment of interstellar dust filaments and magnetic fields. We estimate the misalignment by comparing millimeter-wave dust-polarization measurements from Planck with filamentary structures identified in ...

Associations between Scattering Screens and Interstellar Medium Filaments [PDF]
The Astrophysical JournalPulsar scintillation can be used to measure small-scale structure in the Galaxy, but little is known about the specific interstellar medium (ISM) features that cause scintillation.

Deep Learning for Position Angle Quantification Applied to Interstellar Filaments
The Astronomical JournalStudying filamentary structures opened a door for understanding the conditions of star formation and interstellar medium properties. Present-day algorithms for identifying filaments and their orientations require careful individual parameterization for ...

Aspect ratios of far-infrared and Hi filaments in the diffuse interstellar medium at high Galactic latitudes [PDF]
Astronomy & Astrophysics, 2023 Dusty magnetized structures observable in the far-infrared (FIR) at high Galactic latitudes are ubiquitous and found to be closely related to HI filaments with coherent velocity structures. Considering dimensionless morphological characteristics based on

Hierarchical structure of the interstellar molecular clouds and star formation [PDF]
Open Astronomy, 2017 Properties of the hierarchical structures of interstellar molecular clouds are discussed. Particular attention is paid to the statistical correlations between velocity dispersion and size, and between the magnetic field strength and gas density.
