Biogenic, urban, and wildfire influences on the molecular composition of dissolved organic compounds in cloud water [PDF]
Atmospheric Chemistry and Physics, 2017 Organic aerosol formation and transformation occurs within aqueous aerosol and cloud droplets, yet little is known about the composition of high molecular weight organic compounds in cloud water.

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.

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 ...

Matter and Radiation at Extremes, 2022 The interaction between a molecular cloud and an external agent (e.g., a supernova remnant, plasma jet, radiation, or another cloud) is a common phenomenon throughout the Universe and can significantly change the star formation rate within a galaxy. This

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 12CO, 13CO, H2CO, IRAS 60 and 100 μm images, discernable as velocity components, and have characteristics: <Rfragment>∼ 0.4 pc; <Mfragment>∼ 2 M⊙; <MVRfragment>∼ 1.6 M⊙ km/s pc; Tgas ∼ 11 K; Tdust> ∼ 16 K??. The system

Atmospheric organic matter in clouds: exact masses and molecular formula identification using ultrahigh-resolution FT-ICR mass spectrometry [PDF]
Atmospheric Chemistry and Physics, 2013 Clouds alter the composition of atmospheric aerosol by acting as a medium for interactions between gas- and particulate-phase substances. To determine the cloud water atmospheric organic matter (AOM) composition and study the cloud processing of aerosols,
