A multifrequency study of the active star forming complex NGC6357. I. Interstellar structures linked to the open cluster Pis24 [PDF]
, 2011 We investigate the distribution of the gas (ionized, neutral atomic and molecular), and interstellar dust in the complex star forming region NGC6357 with the goal of studying the interplay between the massive stars in the open cluster Pis24 and the ...

The Astrophysical Journal Letters, 2023 PHANGS–JWST mid-infrared (MIR) imaging of nearby spiral galaxies has revealed ubiquitous filaments of dust emission in intricate detail. We present a pilot study to systematically map the dust filament network (DFN) at multiple scales between 25 and 400 ...

The effect of ambipolar diffusion on low-density molecular ISM filaments [PDF]
, 2016 The filamentary structure of the molecular interstellar medium and the potential link of this morphology to star formation have been brought into focus recently by high resolution observational surveys.

The Galactic Center Isolated Nonthermal Filaments as Analogs of Cometary Plasma Tails [PDF]
, 1999 We propose a model for the origin of the isolated nonthermal filaments observed at the Galactic center based on an analogy to cometary plasma tails. We invoke the interaction between a large scale magnetized galactic wind and embedded molecular clouds ...

RadFil: A Python Package for Building and Fitting Radial Profiles for Interstellar Filaments [PDF]
The Astrophysical Journal, 2018 Abstract We present RadFil, a publicly available Python package that gives users full control over how to build and fit radial profiles for interstellar filaments. RadFil builds filament profiles by taking radial cuts across the spine of a filament, thereby preserving the radial structure of the filament across its entire length.

Supervised machine learning on Galactic filaments
Astronomy & Astrophysics, 2023 Context. Filaments are ubiquitous in the Galaxy, and they host star formation. Detecting them in a reliable way is therefore key towards our understanding of the star formation process. Aims. We explore whether supervised machine learning can identify filamentary structures on the whole Galactic plane. Methods.

The Astrophysical Journal, 2023 We investigate the thermal condensation caused by a massive object that passes through the interstellar medium with high velocity, and propose a mechanism for creating a filamentary gaseous object, or interstellar contrail.

The Turbulent Interstellar Medium [PDF]
, 2006 An overview is presented of the main properties of the interstellar medium. Evidence is summarized that the interstellar medium is highly turbulent, driven on different length scales by various energetic processes.

Radio spectral properties and the magnetic field of the SNR S147 [PDF]
, 2008 (Abridged) S147 is a large faint shell-type supernova remnant (SNR). Its remarkable spectral break at cm-wavelengths is an important physical property to characterize the SNR evolution.
