Star formation in bright-rimmed clouds. I. Millimeter and submillimeter molecular line surveys
pre-main sequence clouds
2014/12/26
We present the results of the first detailed millimeter and submillimeter molecular line survey of bright-rimmed clouds, observed at FCRAO in the CO (J = 1 → 0), C18O (J = 1 → 0), HCO+ (J = 1 → 0), H1...

We have observed six clouds along the line of sight toward W49A using the Submillimeter Wave Astronomy Satellite and several ground-based observatories. The ortho-H2O 110 → 101 and OH (1665 and 1667 M...
Radio and X-ray images of the SNR G18.8+0.3 interacting with molecular clouds
Radio X-ray images
2014/12/23
New HI images from the VLA Galactic Plane Survey (VGPS) show clear absorption features associated with the supernova remnant (SNR) G18.8+0.3. High-resolution 13CO images reveal that molecular clouds o...
We have observed a 3° × 3° area centered on the M81/M82 group of galaxies using the Robert C. Byrd Green Bank Telescope in a search for analogs to the high-velocity clouds of neutral hydrogen found ar...
The Magellanic Clouds Survey: a Bridge to Nearby Galaxies
Nearby Galaxies Magellanic Clouds
2014/12/22
We outline to the community the value of a Magellanic Clouds Survey that consists of three components: I) a complete-area, high resolution, multi-band UV-near-IR broadband survey; II) a narrowband sur...
Herschel observations of ortho- and para-oxidaniumyl (H2O+) in spiral arm clouds toward Sagittarius B2(M) *,**
H2O+ massive star forming
2014/12/22
H2O+ has been observed in its ortho- and para- states toward the massive star forming core Sgr B2(M), located close to the Galactic center. The observations show absorption in all spiral arm clouds be...
THE MASS DISTRIBUTION OF STARLESS AND PROTOSTELLAR CORES IN GOULD BELT CLOUDS
Ophiuchus Tauru
2014/12/22
Using data from the SCUBA Legacy Catalogue (850 μm) and Spitzer Space Telescope (3.6-70 μm), we explore dense cores in the Ophiuchus, Taurus, Perseus, Serpens, and Orion molecular clouds. We develop a...
We report the results of a large-area study of water vapor along the Orion Molecular Cloud ridge, the purpose of which was to determine the depth-dependent distribution of gas-phase water in dense mol...
Probing chemical evolution in molecular clouds with millimeter -wave observations
Cereal chemistry The interstellar medium Millimeter wavelength Molecular emission Dynamics Temperature observation The density of hydrogen molecules
2014/12/9
We present results for a study of gas-phase and grain chemical processes in the dense interstellar medium (ISM) using millimeter-wavelength observations of the pure rotational transitions of molecules...
The Turbulence Spectrum of Molecular Clouds in the Galactic Ring Survey: A Density-Dependent PCA Calibration
Turbulence Spectrum Molecular Clouds Galactic Ring Survey
2011/10/13
Turbulence plays a major role in the formation and evolution of molecular clouds. The problem is that turbulent velocities are convolved with the density of an observed region. To correct for this con...

STABILITY OF THE PROTOGALACTIC CLOUDS：i. fIELD LEHGTH IN THE ADIABATIC MODELS
PROTOGALACTIC CLOUDS i. fIELD LEHGTH ADIABATIC MODELS
2009/3/19
All gasdynamical models for the evolution of gaseous content of
galaxies assume that cooling from the hot, virialized phase to the cold phase occured
through some sort of thermal instability. Subseq...
