The chemistry and kinematics of two molecular clouds near Sagittarius A*
(Oxford University Press, 2016)
We have analysed the chemical and kinematic properties of the 20 and 50 km s(-1) molecular clouds in the Central Molecular Zone of the Milky Way Galaxy, as well as those of the molecular ridge bridging these two clouds. ...
Millimeter-wave Line Ratios and Sub-beam Volume Density Distributions
(IOP Publishing, 2017)
We explore the use of mm-wave emission line ratios to trace molecular gas density when observations integrate over a wide range of volume densities within a single telescope beam. For observations targeting external galaxies, ...
The Chemistry and Kinematics of Two Molecular Clouds near Sagittarius A
(Royal Astronomical Society, 2016-08-09)
We have analysed the chemical and kinematic properties of the 20 and 50 km s−1 molecular clouds in the Central Molecular Zone of the Milky Way Galaxy, as well as those of the molecular ridge bridging these two clouds. Our ...
Physical properties of molecular clouds in the southern outer Galaxy
(1997)
We have used a deep CO survey of the third galactic quadrant (May et al. 1993) to derive the physical properties of molecular clouds in the outer Galaxy. Within the range of this survey, from 194° to 270° in galactic ...
ALMA Observations of Ethyl Formate toward Orion KL
(Institute of Physics Publishing, 2019)
Orion KL is one of the prime templates of astrochemical and prebiotic chemical studies. We wish to explore more organic molecules with increasing complexity in this region. In particular, we have searched for one of the ...
Deuteration in infrared dark clouds
(Oxford University Press, 2016)
Much of the dense gas in molecular clouds has a filamentary structure but the detailed structure and evolution of this gas is poorly known. We have observed 54 cores in infrared dark clouds (IRDCs) using N2H+ (1-0) and ...
Modelling [CI] emission from turbulent molecular clouds
(Oxford University Press, 2015)
© 2015 The Authors.We use detailed numerical simulations of a turbulent molecular cloud to study the usefulness of the [CI] 609 and 370 μmfine structure emission lines as tracers of cloud structure. Emission from these ...
SPH simulations of clumps formation by dissipative collisions of molecular clouds - II. Magnetic case
(Edp Sciences S A, 2001-12-01)
We performed computer simulations of interstellar cloud-cloud collisions using the three-dimensional smoothed particle magnetohydrodynamics method. In order to study the role of the magnetic field on the process of ...
