Molecular Clouds in External Galaxies [PDF]

Symposium - International Astronomical Union, 1985
Observations of the large-scale distribution of molecular clouds in external galaxies offer a unique opportunity for investigating galactic evolution. New generations of stars form in these dense regions, and the most massive of these stars recycle their processed interiors into the interstellar medium.

Galaxy chemical evolution models: The role of molecular gas formation [PDF]

, 2017
In our classical grid of multiphase chemical evolution models, star formation in the disc occurs in two steps: first, molecular gas forms, and then stars are created by cloud-cloud collisions or interactions of massive stars with the surrounding ...

Aperture Synthesis Observations of CO, HCN, and 89GHz Continuum Emission toward NGC 604 in M 33: Sequential Star Formation Induced by Supergiant Hii region

, 2010
We present the results from new Nobeyama Millimeter Array observations of CO(1-0), HCN(1-0), and 89-GHz continuum emissions toward NGC 604, known as the supergiant H ii region in a nearby galaxy M 33.

Molecular Lines of 13 Galactic Infrared Bubble Regions

, 2016
We investigated the physical properties of molecular clouds and star formation processes around infrared bubbles which are essentially expanding HII regions. We performed observations of 13 galactic infrared bubble fields containing 18 bubbles.

On the Flux–Intensity Relation of Molecular Clouds

The Astrophysical Journal Letters
In this work, we report a study on the relationship between flux and intensity for molecular clouds. Our analysis is established on high-quality CO images from the Milky Way Imaging Scroll Painting project.

Masses, luminosities and dynamics of galactic molecular clouds [PDF]

Star formation in galaxies takes place in molecular clouds and the Milky Way is the only galaxy in which it is possible to resolve and study the physical properties and star formation activity of individual clouds. The masses, luminosities, dynamics, and

High Excitation Molecular Gas in the Magellanic Clouds

, 2005
We present the first survey of submillimeter CO 4-3 emission in the Magellanic Clouds. The survey is comprised of 15 6'x6' maps obtained using the AST/RO telescope toward the molecular peaks of the Large and Small Magellanic Clouds.

Examining Turbulence in Galactic Molecular Clouds. I. A Statistical Analysis of Velocity Structures

The Astrophysical Journal
We present a systematic analysis of the velocity structure functions (VSFs) of 167 molecular clouds with angular sizes greater than ~176 arcmin ^2 in three sectors of the Galactic midplane.
