Impact of Supernovae on the Interstellar Medium and the Heliosphere

, 2017
The effect of supernovae on their environment is discussed in general and on the heliosphere in particular. It is shown that supernovae generate turbulence on scales of the order of 100 parsecs (pc), which leads to the formation of structures in the ...

Structure and Fragmentation Scale of a Massive Star-forming Filament in NGC 6334: High-resolution Mid-infrared Absorption Imaging with JWST

The Astrophysical Journal Letters
Dense filaments are believed to be representative of the initial conditions of star formation in molecular clouds. We have used the MIRI instrument on JWST to image the massive filament NGC 6334M at d  ∼ 1.3 kpc with unprecedented resolution and dynamic ...

On the fragmentation of filaments in a molecular cloud simulation

, 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.

A Catalog of Filaments in the Central Molecular Zone

The Astrophysical Journal Supplement Series
We present a catalog of 1.28 GHz radio filaments observed by MeerKAT over the innermost 200 pc of the Galaxy (roughly ±1 $\mathop{.}\limits^{\unicode{x000b0}}$ 5), which includes the central molecular zone.

Microlensing by Gas Filaments

, 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.

Probing the Magnetic Fields and Dust Properties in the Young Embedded Star-forming Region AFGL 6366S Using Near-infrared and Optical Linear Polarimetry

The Astrophysical Journal
We present near-infrared (NIR) and optical linear polarimetry toward the partially embedded cluster AFGL 6366S. The polarization ranges from 0.44% to 10.3% in NIR and from 0.16% to 11.22% in the optical bands. The position angle spans 1°−179° in both the

The Milky Way atlas for linear filaments

Context. Filamentary structure is important for the ISM and star formation. Galactic distribution of filaments may regulate the star formation rate in the Milky Way.
