On the Stability of Interstellar Neutral Hydrogen Clouds at Large Z-heights
The Astrophysical JournalGalactic 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.

A Pan-galaxy Study of Synthetic Giant Molecular Filaments: A Turbulence-dominated Life Cycle
The Astrophysical Journal Supplement SeriesRecent 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

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

The Young Ages of 70 μm Dark Clumps Inferred from Carbon Chain Chemistry
The Astrophysical JournalThe physical conditions of the earliest environment of high-mass star formation are currently poorly understood. To that end, we present observations of the carbon chain molecules HC _5 N, CCS, and HC _7 N in the 22–25 GHz band toward 12 high-mass 70 μ m

Hierarchical Structure and Self-gravity in the Rosette Molecular Cloud
The Astrophysical JournalWe analyze the hierarchical structure in the Rosette molecular cloud using ^13 CO J = 1–0 data from the Milky Way Imaging Scroll Painting survey with a nonbinary Dendrogram algorithm that allows multiple branches to emerge from parent structures. A total

Hierarchical Structure and Self-gravity in the Maddalena Giant Molecular Cloud
The Astrophysical JournalIn 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 ...
