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, ...
Morphological Properties of the Crab Nebula: A Detailed Multiwavelength Study Based on New VLA, HST, Chandra, and XMM-Newton Images
(IOP Publishing, 2017-04)
We present a detailed analysis of the morphological properties of the Crab Nebula across the electromagnetic spectrum based on new and previous high-quality data from radio to X-rays. In the radio range we obtained an image ...
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. ...
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 ...
The diffuse molecular component in the nuclear bulge of the Milky Way
(EDP Sciences, 2018)
Context. The bulk of the molecular gas in the central molecular zone (CMZ) of the Galactic center region shows warm kinetic temperatures, ranging from > 20 K in the coldest and densest regions (n similar to 10(4-5) cm(-3)) ...
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 ...
