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.

[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

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 ...

ALMA Observations of a Quiescent Molecular Cloud in the Large Magellanic Cloud [PDF]
, 2017 We present high-resolution (sub-parsec) observations of a giant molecular cloud in the nearest star-forming galaxy, the Large Magellanic Cloud. ALMA Band 6 observations trace the bulk of the molecular gas in $^{12}$CO(2-1) and high column density regions

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.

FORMATION OF MASSIVE MOLECULAR CLOUD CORES BY CLOUD-CLOUD COLLISION [PDF]
The Astrophysical Journal, 2013 Recent observations of molecular clouds around rich massive star clusters including NGC3603, Westerlund 2, and M20 revealed that the formation of massive stars could be triggered by a cloud-cloud collision. By using three-dimensional, isothermal, magnetohydrodynamics simulations with the effect of self-gravity, we demonstrate that massive ...

An Ice Age JWST inventory of dense molecular cloud ices [PDF]
Nature Astronomy, 2023 Icy grain mantles are the main reservoir of the volatile elements that link chemical processes in dark, interstellar clouds with the formation of planets and the composition of their atmospheres.
