H II regions, infrared dark molecular clouds and the local geometry of the Milky Way's nuclear star-forming ring
H. S. Liszt
To interpret the galactic center H II region complexes as constituents of a barred galaxy's nuclear star-forming ring, we compare 18cm VLA radiocontinuumm, MSX IR and 2.6mm…
A CO J=1-0 Survey of common optical/uv absorption sightlines
H. S. Liszt
Context: Over the past thirty years a wealth of observations of CO and other molecules in optical/uv absorption in diffuse clouds has accumulated for which no comparable CO emissio…
Limits on chemical complexity in diffuse clouds: search for CH3OH and HC5N absorption
H. S. Liszt, J. Pety, R. Lucas
Context: An unexpectedly complex polyatomic chemistry exists in diffuse clouds, allowing detection of species such as C2H, C3H2, H2CO and NH3 which have relative abundances that ar…
Imaging galactic diffuse gas: Bright, turbulent CO surrounding the line of sight to NRAO150
Jérôme Pety, Robert Lucas, Harvey S. Liszt
To understand the environment and extended structure of the host galactic gas whose molecular absorption line chemistry, we previously observed along the microscopic line of sight…
Formation, fractionation and excitation of carbon monoxide in diffuse clouds
H. S. Liszt
Aims: Our aims are threefold: a) To compare the and mm-wave results; b) to interpret 13CO and 12CO abundances in terms of the physical processes which separately and jointly d…
Mm-wave HCO+, HCN and CO absorption toward NGC1052
H. Liszt, R. Lucas
We used the Plateau de Bure Interferometer to observe 3mm J=1-0 absorption lines of \hcop, HCN and CO toward the core of the nearby elliptical, megamaser-host galaxy NGC1052. Th…
