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…
Physical structure of the photodissociation regions in NGC 7023. Observations of gas and dust emission with Herschel
M. Köhler, E. Habart, H. Arab +16
The determination of the physical conditions in molecular clouds is a key step towards our understanding of their formation and evolution of associated star formation. We investiga…
Revised spectroscopic parameters of SH from ALMA and IRAM 30 m observations
Holger S. P. Müller, Javier R. Goicoechea, José Cernicharo +6
Hydrides represent the first steps of interstellar chemistry. Sulfanylium (SH), in particular, is a key tracer of energetic processes. We used ALMA and the IRAM 30 m telescope…
Herschel HIFI observations of O toward Orion: special conditions for shock enhanced emission
Jo-Hsin Chen, Paul F. Goldsmith, Serena Viti +18
We report observations of molecular oxygen (O) rotational transitions at 487 GHz, 774 GHz, and 1121 GHz toward Orion Peak A. The O2 lines at 487 GHz and 774 GHz are detected at…
First detection of [N II] 205 micrometer absorption in interstellar gas
C. M. Persson, M. Gerin, B. Mookerjea +8
We present high resolution [NII] 205 micrometer ^3P_1-^3P_0 spectra obtained with Herschel-HIFI towards a small sample of far-infrared bright star forming regions in the Galactic p…
