Filamentary Hierarchies and Superbubbles: Galactic Multiscale Magnetohydrodynamic Simulations of Giant Molecular Cloud to Star Cluster Formation

The Astrophysical Journal
There is now abundant observational evidence that star formation is a highly dynamical process that connects filament hierarchies and supernova feedback from galaxy-scale kiloparsec filaments and superbubbles to giant molecular clouds (GMCs) on 100 pc ...

Variations of Interstellar Gas-to-dust Ratios at High Galactic Latitudes

The Astrophysical Journal
Interstellar dust at high Galactic latitudes can influence astronomical foreground subtraction, produce diffuse scattered light, and soften the UV spectra of quasars.

Physical Properties and H i-to-H2 Transition across Taurus Linear Edge

The Astrophysical Journal
Studying the atomic-to-molecular transition is essential for understanding the evolution of the interstellar medium. The linear edge of the Taurus molecular cloud, clearly identified in the ^13 CO(1–0) intensity map, serves as an ideal site for ...

Voyager 1 Electron Densities in the Very Local Interstellar Medium to beyond 160 au

The Astrophysical Journal Letters
The two Voyager spacecraft have been exploring the interstellar medium beyond the heliopause since 2012 (Voyager 1) and 2018 (Voyager 2). Electron plasma oscillations and a quasi-thermal noise line at the electron plasma frequency have enabled the ...

A New Constraint on the Relative Disorder of Magnetic Fields between Neutral Interstellar Medium Phases

The Astrophysical Journal
Utilizing Planck polarized dust emission maps at 353 GHz and large-area maps of the neutral hydrogen (H i ) cold neutral medium (CNM) fraction ( f _CNM ), we investigate the relationship between dust polarization fraction ( p _353 ) and f _CNM in the ...
