On the fragmentation of filaments in a molecular cloud simulation [PDF]

, 2018
Context. The fragmentation of filaments in molecular clouds has attracted a lot of attention recently as there seems to be a close relation between the evolution of filaments and star formation.

The Formation of Milky Way “Bones”: Ubiquitous HI Narrow Self-absorption Associated with CO Emission

The Astrophysical Journal Letters
Long and skinny molecular filaments running along Galactic spiral arms are known as “bones,” since they make up the skeleton of the Milky Way. However, their origin is still an open question.

Microlensing by Gas Filaments [PDF]

, 2005
Gas in the interstellar medium is generally organized in filamentary structures, which may also be relevant for a complementary explanation of the dark matter in the Galactic halo.

Multiscale Mass-assembly Scenario in the High-mass Star-forming Filament IRAS 19368+2239 Observed as Part of the INFANT Survey

The Astrophysical Journal
A multiscale dynamical mass-assembly scenario, where stars form through multiscale fragmentation and hierarchical gas infall from clouds to filaments, clumps, and cores, has been proposed for high-mass star formation, but the precise observational ...

Characterizing interstellar filaments with Herschel in IC 5146 {Letter] [PDF]

, 2011
We provide a first look at the results of the Herschel Gould Belt survey toward the IC 5146 molecular cloud and present a preliminary analysis of the filamentary structure in this region. The column density map, derived from our 70–500 μm Herschel data, reveals a complex network of filaments and confirms that these filaments are the main birth sites of

Plasma Heating by Alfven Wave Filamentation: A Relevant Mechanism in the Solar Corona and the Interstellar Medium

The Astrophysical Journal, 1997
A mechanism for small-scale generation in magnetically dominated, homogeneous space plasmas is proposed, resulting from transverse collapse (filamentation) of weakly nonlinear, circularly polarized Alfven waves. It is argued that waves whose frequencies exceed a magnitude of about 10 Hz can significantly contribute to the heating of open coronal holes ...

Characterizing filaments in regions of high-mass star formation: High-resolution submilimeter imaging of the massive star-forming complex NGC 6334 with ArT\'eMiS [PDF]

, 2016
International audienceHerschel observations of nearby molecular clouds suggest that interstellar filaments and prestellar cores represent two fundamental steps in the star formation process.

Sutra: An Integrated Framework for Identification and Characterization of Filaments in the Interstellar Medium

The Astronomical Journal
Observations of the interstellar medium (ISM) at far-infrared and submillimeter wavelengths reveal a complex filamentary structure of dust and gas, which plays a pivotal role in both low- and high-mass star formation.
