A UNIFORM CATALOG OF MOLECULAR CLOUDS IN THE MILKY WAY [PDF]
, 2016 The all-Galaxy CO survey of Dame et al. is by far the most uniform, large-scale Galactic CO survey. Using a dendrogram-based decomposition of this survey, we present a catalog of 1064 massive molecular clouds throughout the Galactic plane.

Understanding the Kinetic Energy Deposition within Molecular Clouds
The Astrophysical Journal, 2023 According to the structures traced by ^13 CO spectral lines within ^12 CO molecular clouds (MCs), we investigate the contributions of their internal gas motions and relative motions to the total velocity dispersions of ^12 CO MCs. Our samples of 2851 ^12

Giant Molecular Clouds in M31. I. Molecular Cloud Properties [PDF]
The Astrophysical Journal, 2007 We present Berkeley Illinois Maryland Association (BIMA) millimeter interferometer observations of giant molecular clouds (GMCs) along a spiral arm in M31. The observations consist of a survey using the compact configuration of the interferometer and follow-up, higher-resolution observations on a subset of the detections in the survey.

SILCC-Zoom: the dynamic and chemical evolution of molecular clouds [PDF]
, 2017 We present 3D ‘zoom-in’ simulations of the formation of two molecular clouds out of the galactic interstellar medium. We model the clouds – identified from the SILCC simulations – with a resolution of up to 0.06 pc using adaptive mesh refinement in ...

The energetics of molecular clouds. II - The S140 molecular cloud
The Astrophysical Journal, 1978 Techniques of analysis which allow estimates of kinetic temperature, gas density, gas cooling rate, and dust cooling rate are applied to the S140 molecular cloud. Maps of this cloud in various molecular lines are examined which reveal the existence of a strong temperature and density peak near the H-alpha rim and the presence of a strong near-IR source

OBSERVATIONAL EVIDENCE OF DYNAMIC STAR FORMATION RATE IN MILKY WAY GIANT MOLECULAR CLOUDS [PDF]
, 2016 Star formation on galactic scales is known to be a slow process, but whether it is slow on smaller scales is uncertain. We cross-correlate 5469 giant molecular clouds (GMCs) from a new all-sky catalog with 256 star-forming complexes (SFCs) to build a ...

Characterizing the 3D Structure of Molecular Cloud Envelopes in the Cloud Factory Simulations
The Astrophysical JournalWe leverage recent numerical simulations of highly resolved star-forming regions in a Milky Way–like galaxy to explore the nature of extended gaseous envelopes around molecular clouds.

Review of Zeeman Effect Observations of Regions of Star Formation
Frontiers in Astronomy and Space Sciences, 2019 The Zeeman effect is the only observational technique available to measure directly the strength of magnetic fields in regions of star formation. This chapter reviews the physics of the Zeeman effect and its practical use in both extended gas and in ...

The energetics of molecular clouds. III - The S235 molecular cloud
The Astrophysical Journal, 1981 The molecular cloud associated with the S235 H II region has been studied by means of molecular lines and near-infrared observations. The cloud consists of two components, one of which partly surrounds the S235 H II region. The other component contains a dense, hot region of active star formation, marked by self-reversed CO profiles, compact H II ...
