The Molecular Cloud Lifecycle [PDF]
Space Science Reviews, 2020 Giant molecular clouds (GMCs) and their stellar offspring are the building blocks of galaxies. The physical characteristics of GMCs and their evolution are tightly connected to galaxy evolution.

Molecular clouds in the Galaxy [PDF]
The Astrophysical Journal, 1975 The J = 1 → 0 emission of CO has been surveyed in the galactic plane between ℓ = -10° and +90° with a U beam sampling every degree. Molecular clouds emitting in the CO line are plentiful over the inner region of the Galaxy. Their greatest number occurs in the galactic nucleus and at a radius of 5.5 kpc—a distribution similar to radio H II regions and ...

Evolving Molecular Cloud Structure and the Column Density Probability Distribution Function [PDF]
, 2014 The structure of molecular clouds can be characterized with the probability distribution function (PDF) of the mass surface density. In particular, the properties of the distribution can reveal the nature of the turbulence and star formation present ...

Cloud-cloud Collision in the Galactic Center 50 km s$^{-1}$ Molecular Cloud [PDF]
, 2015 We performed a search of star-forming sites influenced by external factors, such as SNRs, HII regions, and cloud-cloud collisions, to understand the star-forming activity in the Galactic center region using the NRO Galactic Center Survey in SiO $v=0, J=2-

Supergiant Shells and Molecular Cloud Formation in the LMC [PDF]
, 2012 We investigate the influence of large-scale stellar feedback on the formation of molecular clouds in the Large Magellanic Cloud (LMC). Examining the relationship between HI and 12CO(J=1-0) in supergiant shells (SGSs), we find that the molecular fraction ...

Molecular Clouds in Spiral Galaxies [PDF]
Symposium - International Astronomical Union, 1983 A large observational program investigating the 2.6 mm CO line in spiral galaxies is being conducted by myself and Nick Scoville using the 14 m telescope of the Five College Radio Astronomy Observatory (HPBW = 50″). Thus far we have observed 46 galaxies of types Sa, Sb, Sc and Irr, detected 31, and mapped 16.

A Bubbling Nearby Molecular Cloud: COMPLETE Shells in Perseus [PDF]
, 2011 We present a study on the shells (and bubbles) in the Perseus molecular cloud using the COMPLETE survey large-scale 12CO(1-0) and 13CO(1-0) maps. The twelve shells reported here are spread throughout most of the Perseus cloud and have circular or arc ...

An Ice Age JWST inventory of dense molecular cloud ices [PDF]
Nature Astronomy, 2023 Icy grain mantles are the main reservoir of the volatile elements that link chemical processes in dark, interstellar clouds with the formation of planets and the composition of their atmospheres.

Molecular Cloud Populations in the Context of Their Host Galaxy Environments: A Multiwavelength Perspective [PDF]
Astronomical Journal, 2022 We present a rich, multiwavelength, multiscale database built around the PHANGS–ALMA CO (2 − 1) survey and ancillary data. We use this database to present the distributions of molecular cloud populations and subgalactic environments in 80 PHANGS galaxies,
