Comparing absorption from classic tracers of the diffuse interstellar medium at optical and radio wavelengths along the same sightlines
Harvey Liszt
% aims To compare information gained from radio and optical absorption line profiles from the diffuse interstellar medium along the same sightline % methods We compare new and exis…
CO+ as a probe of the origin of CO in diffuse interstellar clouds
Maryvonne Gerin, Harvey Liszt
The chemistry of the diffuse interstellar medium is driven by the combined influences of cosmic rays, ultraviolet (UV) radiation, and turbulence. Previously detected at the outer e…
Reconciling X-ray and 21cm HI absorption gas column densities toward obscured AGN
Harvey Liszt
Hydrogen column densities inferred from X-ray absorption are typically 5 - 30 times larger than the neutral atomic hydrogen column densities derived from 21cm HI absorption toward…
Quantitative inference of the column densities from 3 mm molecular emission: A case study towards Orion B
Pierre Gratier, Jérôme Pety, Emeric Bron +21
Molecular hydrogen being unobservable in cold molecular clouds, the column density measurements of molecular gas currently rely either on dust emission observation in the far-IR or…
Tracers of the ionization fraction in dense and translucent gas: I. Automated exploitation of massive astrochemical model grids
Emeric Bron, Evelyne Roueff, Maryvonne Gerin +21
The ionization fraction plays a key role in the physics and chemistry of the neutral interstellar medium, from controlling the coupling of the gas to the magnetic field to allowing…
CO emission and CO hotspots in diffuse molecular gas
Harvey S Liszt
We observed 3mm \cotw, \coth, \coei, \hcop, HCN and CS emission from diffuse molecular gas along sightlines with \EBV\ 0.1 - 1 mag. Directions were mostly chosen for t…
