G321.93-0.01: A Rare Site of Multiple Hub-filament Systems with Evidence of Collision and Merging of Filaments

open access: yesThe Astronomical Journal
Hub-filament systems (HFSs) are potential sites of massive star formation (MSF). To understand the role of filaments in MSF and the origin of HFSs, we conducted a multiscale and multiwavelength observational investigation of the molecular cloud G321.93–0.

Intermittency and Anisotropy in the Ionized Interstellar Medium [PDF]

open access: yes, 2017
The discovery of pulsars was closely followed by the discovery of dispersion and scattering in the interstellar plasma (ionized interstellar medium - IISM).

Ionized interstellar froth in irregular galaxies [PDF]

open access: yes, 1990
The warm interstellar medium of galaxies is a complicated place. It is often full of holes, neutral and ionized loops and shells, and diffuse ionized gas.

Bubbles and holes in the interstellar medium [PDF]

open access: yes, 1996
Studies of the HI in nearby galaxies now clearly begin to show the effects of star formation on the interstellar medium. Holes, filaments, expanding motions and other anomalous velocity signatures are clearly apparent in sensitive observations of the HI ...

Galactic Large-scale Filaments Resident in Asymmetric Environments: Clues from Cross-filament Profiles of Density and Temperature

open access: yesThe Astrophysical Journal
Large-scale filaments ubiquitously exist in the Galactic interstellar medium, and their radial profiles offer insights into their formation mechanisms. We present a statistical analysis of molecular hydrogen column density (N(H _2 )) and dust temperature

Impact of Supernovae on the Interstellar Medium and the Heliosphere [PDF]

open access: yes, 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 ...

ACES: The Magnetic Field in Large Filaments in the Galactic Center

open access: yesThe Astrophysical Journal
The Galactic center (GC) is an extreme region of the Milky Way that is host to a complex set of thermal and nonthermal structures. In particular, the GC contains high-density gas and dust that is collectively referred to as the Central Molecular Zone ...

Wave Structure within HI Filaments at High Galactic Latitude and the Nature of “Clouds” in Interstellar Space [PDF]

open access: yesSymposium - International Astronomical Union, 1991
Large amplitude waves have been found in the morphology and velocity patterns of several long filaments of HI at high latitude. HI in the filaments is controlled by magnetic fields and the velocity patterns and morphology bear the hallmarks of Alfvén waves.

Planck intermediate results: XXXIII. Signature of the magnetic field geometry of interstellar filaments in dust polarization maps [PDF]

open access: yes, 2016
© ESO, 2016.Planck observations at 353 GHz provide the first fully sampled maps of the polarized dust emission towards interstellar filaments and their backgrounds (i.e., the emission observed in the surroundings of the filaments).
