Herschel Survey of Galactic OH+, H2O+, and H3O+: Probing the Molecular Hydrogen Fraction and Cosmic-Ray Ionization Rate
Nick Indriolo, D. A. Neufeld, M. Gerin +19
In diffuse interstellar clouds the chemistry that leads to the formation of the oxygen bearing ions OH+, H2O+, and H3O+ begins with the ionization of atomic hydrogen by cosmic rays…
[CII] absorption and emission in the diffuse interstellar medium across the Galactic Plane
M. Gerin, M. Ruaud, J. R. Goicoechea +10
Ionized carbon is the main gas-phase reservoir of carbon in the neutral diffuse interstellar medium and its 158 micron fine structure transition [CII] is the most important cooling…
Chemical probes of turbulence in the diffuse medium: the TDR model
Benjamin Godard, Edith Falgarone, Guillaume Pineau Des Forêts
Context. Tens of light hydrides and small molecules have now been detected over several hundreds sight lines sampling the diffuse interstellar medium (ISM) in both the Solar neighb…
OH+ in astrophysical media: state-to-state formation rates, Einstein coefficients and inelastic collision rates with He
S. Gomez-Carrasco, B. Godard, F. Lique +9
The rate constants required to model the OH observations in different regions of the interstellar medium have been determined using state of the art quantum methods. First, sta…
Ubiquitous argonium (ArH) in the diffuse interstellar medium -- a molecular tracer of almost purely atomic gas
Peter Schilke, David A. Neufeld, Holger S. P. Müller +14
We describe the assignment of a previously unidentified interstellar absorption line to ArH and discuss its relevance in the context of hydride absorption in diffuse gas with a…
Widespread Rotationally-Hot Hydronium Ion in the Galactic Interstellar Medium
D. C. Lis, P. Schilke, E. A. Bergin +11
We present new observations of the (6,6) and (9,9) inversion transitions of the hydronium ion toward Sagittarius B2(N) and W31C. Sensitive observations toward Sagittarius B2(N) sho…
