The Molecular Cloud Lifecycle. [PDF]

open access: yesSpace Sci Rev, 2020
Giant 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.

Compression and ablation of the photo-irradiated molecular cloud the Orion Bar. [PDF]

open access: yesNature, 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]

open access: yesAstron 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

ALMA Observations of a Quiescent Molecular Cloud in the Large Magellanic Cloud [PDF]

open access: yes, 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]

open access: yesAtmospheric 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.

A Bubbling Nearby Molecular Cloud: COMPLETE Shells in Perseus [PDF]

open access: yes, 2011
We present a study on the shells (and bubbles) in the Perseus molecular cloud using the COMPLETE survey large-scale 12CO(1-0) and 13CO(1-0) maps. The twelve shells reported here are spread throughout most of the Perseus cloud and have circular or arc ...

Molecular clouds in the Galaxy [PDF]

open access: greenThe Astrophysical Journal, 1975
The J = 1 → 0 emission of CO has been surveyed in the galactic plane between ℓ = -10° and +90° with a U beam sampling every degree. Molecular clouds emitting in the CO line are plentiful over the inner region of the Galaxy. Their greatest number occurs in the galactic nucleus and at a radius of 5.5 kpc—a distribution similar to radio H II regions and ...

An Ice Age JWST inventory of dense molecular cloud ices [PDF]

open access: yesNature 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.
