Multi-line characterization of whole molecular clouds using stratified random sampling [PDF]
EPJ Web of Conferences, 2022 We have developed a new technique to characterize the multi-line emission from molecular clouds using statistical sampling. Our method uses available extinction maps to select a relatively small sample of cloud positions that cover the full range of ...

The Role of Magnetic Field in Molecular Cloud Formation and Evolution [PDF]
Frontiers in Astronomy and Space Sciences, 2019 We review the role that magnetic field may have on the formation and evolution of molecular clouds. After a brief presentation and main assumptions leading to ideal MHD equations, their most important correction, namely the ion-neutral drift is described.

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.

Mapping Distances across the Perseus Molecular Cloud Using CO Observations, Stellar Photometry, and Gaia DR2 Parallax Measurements [PDF]
Astrophysical Journal, 2018 We present a new technique to determine distances to major star-forming regions across the Perseus Molecular Cloud, using a combination of stellar photometry, astrometric data, and 12CO spectral-line maps. Incorporating the Gaia DR2 parallax measurements

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.

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 ...
