Context. The infall of gas from outside natal cores has proven to feed protostars after the
main accretion phase (Class 0). This changes our view of star formation to a picture that …

Context. Despite their variety of scales throughout the interstellar medium, filaments in
nearby low-mass clouds appear to have a characteristic width of∼ 0.1 pc from the analysis …

High-resolution observations of the Perseus B5" core" have previously revealed that this
subsonic region actually consists of several filaments that are likely in the process of forming …

The study of the development of structures on multiple scales in the cold interstellar medium
has experienced rapid expansion in the past decade, on both the observational and the …

Filaments are an ubiquitous feature of molecular clouds, and appear to play a critical role in
assembling the material to form stars. The dominant filaments are observed to have a rather …

Fragmentation contributes to the formation and evolution of stars. Observationally, high-
mass stars are known to form multiple-star systems, preferentially in cluster environments …

The onset of star formation is set by the collapse of filaments in the interstellar medium. From
a theoretical point of view, an isolated cylindrical filament forms cores via the edge effect …

Filamentary structures identified in far-infrared observations of molecular clouds are typically
found to have full widths at half-maximum. However, the physical explanation for this …

We study the formation, evolution, and collapse of dense cores by tracking structures in a
magnetohydrodynamic simulation of a star-forming cloud. We identify cores using the …

Context. Filamentary structures are an important part of star-forming interstellar clouds. The
properties of filaments hold clues to their formation mechanisms and their role in the star …
