The Global Evolution of Giant Molecular Clouds II: The Role of Accretion [PDF]

, 2011
We present virial models for the global evolution of giant molecular clouds. Focusing on the presence of an accretion flow, and accounting for the amount of mass, momentum, and energy supplied by accretion and star formation feedback, we are able to ...

Chiral and Molecular Recognition through Protonation between Aromatic Amino Acids and Tripeptides Probed by Collision-Activated Dissociation in the Gas Phase

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 ...

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.

Statistical study of dust properties in LMC molecular clouds [PDF]

, 2010
The objective of this paper is to construct a catalog providing the dust properties and the star formation efficiency (SFE) of the molecular clouds in the Large Magellanic Cloud (LMC).

Chemistry of Molecular Clouds [PDF]

International Astronomical Union Colloquium, 1989
AbstractA discussion is presented of the chemistry of quiescent molecular clouds, and the effects of the presence of polycyclic aromatic hydrocarbon molecules and of cosmic-ray induced ultraviolet photons are examined. A comparison is made with the chemistry occurring in molecular clouds that are subjected to shocks and the differences between ...

The simulation of molecular clouds formation in the Milky Way [PDF]

, 2012
Using 3D hydrodynamic calculations we simulate formation of molecular clouds in the Galaxy. The simulations take into account molecular hydrogen chemical kinetics, cooling and heating processes.

Molecular clouds in M82

The Astrophysical Journal, 1984
CO observations of the peculiar galaxy M82 have been made at 79 positions using the 14 m FCRAO telescope (HPBW = 50'') in order to obtain a fully sampled map of the central 2 kpc as well as the radial distribution of molecular gas out to 3 kpc along the major axis.

Kinematic Distances to Molecular Clouds identified in the Galactic Ring Survey [PDF]

, 2009
Kinematic distances to 750 molecular clouds identified in the 13CO J=1-0 Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey (BU-FCRAO GRS) are derived assuming the Clemens rotation curve of the Galaxy.

Giant Molecular Clouds in M31. I. Molecular Cloud Properties [PDF]

The Astrophysical Journal, 2007
We present Berkeley Illinois Maryland Association (BIMA) millimeter interferometer observations of giant molecular clouds (GMCs) along a spiral arm in M31. The observations consist of a survey using the compact configuration of the interferometer and follow-up, higher-resolution observations on a subset of the detections in the survey.
