A Multiscale Molecular and Atomic Gas View on the H ii Region N113 in the Large Magellanic Cloud: Evidence for High-mass Star Formation Triggered by Supersonically Colliding H i Flows

The Astrophysical Journal
The Large Magellanic Cloud (LMC) exhibits vigorous high-mass star formation, including the H ii regions of 30 Dor, which is the most active site of star formation in the Local Group.

On the Stability of Interstellar Neutral Hydrogen Clouds at Large Z-heights

The Astrophysical Journal
Galactic neutral hydrogen (H i ) data drawn from several large-scale surveys have been used to study 32 small clouds found between Galactic longitudes 70° and 140° and latitudes −20° and −45°.

Cloud-cloud collisions in the interstellar medium

The Astrophysical Journal, 1980
Results are presented from time-dependent numerical simulations of cloud-cloud collisions in the interstellar medium. Special emphasis is placed on physically detailed models of cloud collisions. The numerical simulations include heating, cooling, thermal conductivity, self-gravity, and molecule formation; magnetic fields have been neglected.

Gas Kinematics and Dynamics of Carina Pillars: A Case Study of G287.76-0.87

The Astrophysical Journal
We study the kinematics of a pillar, namely G287.76-0.87, using three rotational lines of ^12 CO(5-4), ^12 CO(8-7), ^12 CO(11-10), and a fine structure line of [O i ] 63 μ m in southern Carina observed by SOFIA/GREAT.

A Pan-galaxy Study of Synthetic Giant Molecular Filaments: A Turbulence-dominated Life Cycle

The Astrophysical Journal Supplement Series
Recent surveys of the Galactic plane have revealed dozens of giant molecular filaments (GMFs), with lengths ranging from tens to hundreds of parsecs, yet their origins and life cycles remain debated. In this work, we analyze over 700 GMFs identified from

Hierarchical Structure and Self-gravity in the Maddalena Giant Molecular Cloud

The Astrophysical Journal
In this work, we present data from the Milky Way Imaging Scroll Painting project for the Maddalena giant molecular cloud (GMC). We decompose the ^13 CO emission datacube of the observed region into hierarchical substructures using a modified dendrogram ...

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 ...
