Molecular cloud cores with a high deuterium fraction: Nobeyama single-pointing survey
(IOP Publishing, 2020)
We present the results of a single-pointing survey of 207 dense cores embedded in Planck Galactic Cold Clumps distributed in five different environments (lambda Orionis, Orion A, Orion B, the Galactic plane, and high ...
The CO J = 21 / J = 10 Ratio in the Large Magellanic Cloud
(2001-04-20)
We observed 34 positions throughout the disk of the Large Magellanic Cloud in the CO J = 21 emission line with the Tokyo-Onsala-ESO-Calán 60 cm radio telescope. Comparing the spectra with those of the J = 10 line at the ...
A model for the onset of self-gravitation and star formation in molecular gas governed by galactic forces. II. The bottleneck to collapse set by cloud-environment decoupling
(IOP Publishing, 2020)
In Meidt et al., we showed that gas kinematics on the scale of individual molecular clouds are not entirely dominated by self-gravity but also track a component that originates with orbital motion in the potential of the ...
Distance limits on the bright X-ray emission toward the Galactic center: Evidence for a very hot interstellar medium in the Galactic X-ray bulge
(UNIV CHICAGO PRESS, 2000-12-10)
Observations of the diffuse X-ray background at energies similar to3/4 and 1.5 keV show a large region of enhanced emission around the Galactic center. The origin of this X-ray enhancement is not known, but the best ...
Massive star formation in the GMC G345.5+1.0: spatial distribution of the dust emission
(EDP SCIENCES S A, 2011-10)
Context. Massive condensations in giant molecular clouds (GMCs) are linked to the formation of high mass stars, which are the principal source of heavy elements and UV radiation, playing an important role in the evolution ...
THE EARLY STAGES OF STAR FORMATION IN INFRARED DARK CLOUDS: CHARACTERIZING THE CORE DUST PROPERTIES
(The American Astronomical Society, 2010-05-20)
Identified as extinction features against the bright Galactic mid-infrared background, infrared dark clouds (IRDCs)
are thought to harbor the very earliest stages of star and cluster formation. In order to better characterize ...
STAR-FORMING REGION BBW 36 IN PUPPIS
(SPRINGER/PLENUM PUBLISHERS, 2008-07)
Recent studies of the star formation region BBW 36 and associated molecular clouds are presented. The (CO)-C-12 (1-0) observations, carried out with the 15-m SEST (Swedish-ESO) telescope (Cerro La Silla, Chile), revealed ...
Filament intersections and cold dense cores in Orion A North
(Oxford University Press, 2020)
We studied the filament structures and cold dense cores in OMC-2,3 region in Orion A North molecular cloud using the high-resolution N2H+ (1-0) spectral cube observed with the Atacama Large Millimeter/Submillimeter Array ...
SMASH 1: A very faint globular cluster disrupting in the outer reaches of the LMC?
(IOP Publishing, 2016)
We present the discovery of a very faint stellar system, SMASH 1, that is potentially a satellite of the Large Magellanic Cloud. Found within the Survey of the MAgellanic Stellar History (SMASH), SMASH 1 is a compact (r(h) ...
THE HERschel inventory of the agents of galaxy evolution in the magellanic clouds, a herschel open time key program
(The American Astronomical Society, 2013)
We present an overview of the HERschel Inventory of The Agents of Galaxy Evolution (HERITAGE) in the
Magellanic Clouds project, which is a Herschel Space Observatory open time key program. We mapped the Large
Magellanic ...
