Molecular Clouds in Spiral Galaxies [PDF]

open access: bronzeSymposium - International Astronomical Union, 1983
A large observational program investigating the 2.6 mm CO line in spiral galaxies is being conducted by myself and Nick Scoville using the 14 m telescope of the Five College Radio Astronomy Observatory (HPBW = 50″). Thus far we have observed 46 galaxies of types Sa, Sb, Sc and Irr, detected 31, and mapped 16.

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

open access: yesMolecules, 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 Scaleheight of Giant Molecular Clouds is Less than that of Smaller Clouds [PDF]

open access: yesAstrophys.J. 619 (2005) L159-L162, 2004
We have used an antenna temperature thresholding algorithm on the Bell Laboratories 13CO Milky Way Survey to create a catalog of 1,400 molecular clouds. Of these, 281 clouds were selected for having well-determined kinematic distances. The scaleheight, luminosity, internal velocity dispersion, and size of the cloud sample are analyzed to show that ...

Spiral arm triggering of star formation [PDF]

open access: yes, 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]

open access: yes, 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).

ON THE THEORY OF THE OF-CENTRAL EXPLOSION IN A SPHERICALLY STRATIFIED MEDIUM

open access: yesRadio Physics and Radio Astronomy, 2015
Аn analytical solution for a spherically stratified medium is constructed on the strength of an earlier obtained exact solution of Kompaneets equation for the shock front in a planar stratified medium with the density changing as the hyperbolic tangent ...

Molecular Clouds in the Galactic Plane from l = [59.°75, 74.°75] and b = [−5.°25, +5.°25]

open access: yesThe Astrophysical Journal Supplement Series, 2023
In this paper we present the distribution of molecular gas in the Milky Way Galactic plane from l = [59.75, 74.75]° and b = [−5.25, +5.25]°, using the MWISP ^12 CO/ ^13 CO/C ^18 O emission-line data.

The LEGO Large Program: Constraining the Physics of Line Emission in Galaxy Observations [PDF]

open access: yesEPJ Web of Conferences, 2022
The IRAM Large Program LEGO studies molecular clouds in the Milky Way to constrain the physics controlling molecular line emission in galaxies. This is done by imaging two dozen clouds with setups that provide continuous spectral coverage of about 85–115

OBSERVATIONS OF NON TYPICAL MASERS AT THE RT-22 RADIO TELESCOPE IN 2004–2013

open access: yesRadio Physics and Radio Astronomy, 2017
Purpose: Some peculiarities of emission of Class I methanol masers on the 80–71A+ transition at 95 GHz in sources closely associated with protostar-forming regions and in supernova remnants are studied.
