The formation of molecular clouds [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 In a recent paper, Elmegreen (2000) has made a cogent case, from an observational point of view, that the lifetimes of molecular clouds are comparable to their dynamical timescales. If so, this has important implications for the mechanisms by which molecular clouds form.

The Molecular Cloud Lifecycle [PDF]
Space Science Reviews, 2020 AbstractGiant 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. The macroscopic properties of the interstellar medium propagate into the properties of GMCs condensing out of it, with correlations between e.g.

A Mesofractal Model of Interstellar Cloudiness
Universe, 2022 The interstellar medium (ISM), serving as a background for the propagation of cosmic rays (CRs) and other information carriers, has a complex ragged structure.

Photometry and kinematics of extragalactic star-forming complexes
Open Astronomy, 2022 We investigate spectral and photometric properties of extragalactic star-forming complexes (SFCs). The SFCs were selected in 17 nearby galaxies of a spiral or irregular type, having inclinations less than 45° and distances less than 15 Mpc.

12CO (3–2) High-Resolution Survey (COHRS) of the Galactic Plane: Complete Data Release
The Astrophysical Journal Supplement Series, 2022 We present the full data release of the ^12 CO (3–2) High-Resolution Survey (COHRS), which has mapped the inner Galactic plane over the range of 9.°5 ≤ l ≤ 62.°3 and ∣ b ∣ ≤ 0.°5.

Fragmentation in molecular clouds [PDF]
Symposium - International Astronomical Union, 1991 B209. Fragments are detected in the outer parts of the B209 molecular cloud in a region of density 1000 cm −3 using 12 CO, 13 CO, H 2 CO, IRAS 60 and 100
