Embedded Clusters in Molecular Clouds [PDF]
, 2003 ▪ Abstract Stellar clusters are born embedded within giant molecular clouds (GMCs) and during their formation and early evolution are often only visible at infrared wavelengths, being heavily obscured by dust.

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.

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.

On the structure of molecular clouds [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 We show that the inter-cloud Larson scaling relation between mean volume density and size $ \propto R^{-1}$, which in turn implies that mass $M\propto R^2$, or that the column density $N$ is constant, is an artifact of the observational methods used.

The Molecular Clouds in a Section of the Third Galactic Quadrant: Cloud Catalog
The Astronomical Journal, 2023 We present results of cloud catalogs of ^12 CO, ^13 CO, and C ^18 O ( J = 1–0) in a section of the third Galactic quadrant over (195° < l < 220°, ∣ b ∣ < 5°) from the Milky Way Imaging Scroll Painting project.

Molecular line signatures of cloud–cloud collisions [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Collisions between interstellar gas clouds are potentially an important mechanism for triggering star formation. This is because they are able to rapidly generate large masses of dense gas. Observationally, cloud collisions are often identified in position–velocity (PV) space through bridging features between intensity peaks ...

The dynamical evolution of molecular clouds near the Galactic Centre – II. Spatial structure and kinematics of simulated clouds [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The evolution of molecular clouds in galactic centres is thought to differ from that in galactic discs due to a significant influence of the external gravitational potential.

How Galactic Environment Affects the Dynamical State of Molecular Clouds and Their Star Formation Efficiency [PDF]
Astrophysical Journal, 2019 We investigate how the dynamical state of molecular clouds relates to host galaxy environment and how this impacts the star formation efficiency (SFE) in the Milky Way and seven nearby galaxies.

The lifecycle of molecular clouds in nearby star-forming disc galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2019 It remains a major challenge to derive a theory of cloud-scale ($\lesssim100$ pc) star formation and feedback, describing how galaxies convert gas into stars as a function of the galactic environment.
