Interstellar filaments and star formation [PDF]
Comptes Rendus - Geoscience, 2017 Recent studies of the nearest star-forming clouds of the Galaxy at submillimeter wavelengths with the Herschel Space Observatory have provided us with unprecedented images of the initial conditions and early phases of the star formation process.

Magnetic Misalignment of Interstellar Dust Filaments
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 ...

On the formation of density filaments in the turbulent interstellar medium [PDF]
The Astrophysical Journal, 2019 This study is motivated by recent observations on ubiquitous interstellar density filaments and guided by modern theories of compressible magnetohydrodynamic (MHD) turbulence. The interstellar turbulence shapes the observed density structures.

Galactic star formation with NIKA2 (GASTON): Filament convergence and its link to star formation [PDF]
EPJ Web of Conferences, 2022 In the past decade filaments have been recognised as a major structural element of the interstellar medium, the densest of these filaments hosting the formation of most stars.

On the 3D Curvature and Dynamics of the Musca Filament
The Astrophysical Journal, 2023 Filaments are ubiquitous in the interstellar medium, yet their formation and evolution remain the topic of intense debate. In order to obtain a more comprehensive view of the 3D morphology and evolution of the Musca filament, we model the C ^18 O(2-1 ...

Mapping the Multiphase Structure of H i in the Low-latitude Intermediate-velocity Arch 1
The Astrophysical Journal, 2023 We have analyzed the thermal and turbulent properties of the low-latitude intermediate-velocity Arch 1 (LLIV1). This was accomplished using archival H i emission and absorption data from two 21 cm line surveys: GHIGLS at 9.′4 resolution and DHIGLS at $1^{

Hierarchical structure of the interstellar molecular clouds and star formation
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.
