Compression and ablation of the photo-irradiated molecular cloud the Orion Bar [PDF]
Nature, 2016 The Orion Bar is the archetypal edge-on molecular cloud surface illuminated by strong ultraviolet radiation from nearby massive stars. Our relative closeness to the Orion nebula (about 1,350 light years away from Earth) means that we can study the ...

[Cii] emission from L1630 in the Orion B molecular cloud. [PDF]
Astron Astrophys, 2017 CONTEXT L1630 in the Orion B molecular cloud, which includes the iconic Horsehead Nebula, illuminated by the star system σ Ori, is an example of a photodissociation region (PDR). In PDRs, stellar radiation impinges on the surface of dense material, often

Giant molecular cloud catalogues for PHANGS-ALMA: methods and initial results [PDF]
Monthly notices of the Royal Astronomical Society, 2021 We present improved methods for segmenting CO emission from galaxies into individual molecular clouds, providing an update to the cprops algorithms presented by Rosolowsky & Leroy.

From Diffuse Gas to Dense Molecular Cloud Cores [PDF]
, 2020 Molecular clouds are a fundamental ingredient of galaxies: they are the channels that transform the diffuse gas into stars. The detailed process of how they do it is not completely understood. We review the current knowledge of molecular clouds and their

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.
