Magnetic Misalignment of Interstellar Dust Filaments [PDF]
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]
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 [PDF]
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 ...

Characterizing interstellar filaments withHerschelin IC 5146 [PDF]
Astronomy & Astrophysics, 2011 We provide a first look at the results of the Herschel Gould Belt survey toward the IC5146 molecular cloud and present a preliminary analysis of the filamentary structure in this region. The column density map, derived from our 70-500 micron Herschel data, reveals a complex network of filaments, and confirms that these filaments are the main birth ...

Merging, fragmentation and collapse of interstellar filaments [PDF]
, 2023 Stars have always fascinated people and already decades ago observations showed that low-mass stars originate from filamentary structures. Nevertheless, the formation process of these filaments, as well as their evolution and fragmentation into individual cores, is not yet sufficiently understood.

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.

Fragmentation in interstellar filaments [PDF]
, 2019 Interstellare Filamente sind ein wesentlicher Schritt der Sternentstehung. In den letzten Jahren haben Beobachtungen die analytischen und numerischen Studien aus mehreren Jahrzehnten bewiesen, die gezeigt haben, dass Molekülwolken im interstellaren Medium hochgradig filamentär und Entstehungsorte massearmer Sterne sind.

Aspect ratios of far-infrared and H I filaments in the diffuse interstellar medium at high Galactic latitudes [PDF]
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 ...

Properties of Interstellar Filaments as Derived from Herschel Observations [PDF]
, 2014 We present a scenario for filament formation and evolution motivated by recent observational results of nearby molecular clouds. The analysis of more than 250 filaments observed in 7 regions by the Herschel Gould Belt Survey show that the filaments are ...

Supervised machine learning on Galactic filaments [PDF]
Astronomy & Astrophysics, 2023 Context. Filaments are ubiquitous in the Galaxy, and they host star formation. Detecting them in a reliable way is therefore key towards our understanding of the star formation process. Aims. We explore whether supervised machine learning can identify filamentary structures on the whole Galactic plane. Methods.
