Filamentary Fragmentation and Accretion in High-mass Star-forming Molecular Clouds [PDF]
, 2018 Filamentary structures are ubiquitous in high-mass star-forming molecular clouds. Their relation with high-mass star formation is still to be understood.

The spatial relation between young star clusters and molecular clouds in M51 with LEGUS [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present a study correlating the spatial locations of young star clusters with those of molecular clouds in NGC 5194, in order to investigate the time-scale over which clusters separate from their birth clouds.

Molecules, 2018 Chiral and molecular recognition through protonation was investigated through the collision-activated dissociation (CAD) of protonated noncovalent complexes of aromatic amino acid enantiomers with l-alanine- and l-serine-containing tripeptides using a ...

The integrated properties of the molecular clouds from the JCMT CO(3–2) High-Resolution Survey [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We define the molecular cloud properties of the Milky Way first quadrant using data from the JCMT CO(3–2) High-Resolution Survey. We apply the Spectral Clustering for Interstellar Molecular Emission Segmentation (SCIMES) algorithm to extract objects from

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

Spiral arm triggering of star formation [PDF]
, 2006 We present numerical simulations of the passage of clumpy gas through a galactic spiral shock, the subsequent formation of giant molecular clouds (GMCs) and the triggering of star formation.

Tracing the formation of molecular clouds via [C ii], [C i], and CO emission [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Our understanding of how molecular clouds form in the interstellar medium (ISM) would be greatly helped if we had a reliable observational tracer of the gas flows responsible for forming the clouds. Fine structure emission from singly ionized and neutral

The Milky Way in Molecular Clouds: A New Complete CO Survey [PDF]
, 2000 New large-scale CO surveys of the first and second Galactic quadrants and the nearby molecular cloud complexes in Orion and Taurus, obtained with the CfA 1.2 m telescope, have been combined with 31 other surveys obtained over the past two decades with ...

Helical magnetic fields in molecular clouds? [PDF]
Astronomy & Astrophysics, 2018 Context. Magnetic fields pervade in the interstellar medium (ISM) and are believed to be important in the process of star formation, yet probing magnetic fields in star formation regions is challenging. Aims.
