Origin of CH+ in diffuse molecular clouds warm H2 and ion-neutral drift
Valeska Valdivia, Benjamin Godard, Patrick Hennebelle +3
This paper assesses the roles of the presence of warm H2, and the increased formation rate due to the ion-neutral drift. We performed ideal MHD simulations that include the heating…
Herschel / HIFI spectral line survey of the Orion Bar - Temperature and density differentiation near the PDR surface
Z. Nagy, Y. Choi, V. Ossenkopf-Okada +7
Photon Dominated Regions (PDRs) are interfaces between the mainly ionized and mainly molecular material around young massive stars. Analysis of the physical and chemical structure…
The anatomy of the Orion B Giant Molecular Cloud: A local template for studies of nearby galaxies
Jérôme Pety, Viviana V. Guzmán, Jan H. Orkisz +11
We aim to develop the Orion B Giant Molecular Cloud (GMC) as a local template for interpreting extra-galactic molecular line observations. We use the wide-band receiver at the IRAM…
Planck's Dusty GEMS. II. Extended [CII] emission and absorption in the Garnet at z=3.4 seen with ALMA
N. Nesvadba, R. Kneissl, R. Canameras +9
We present spatially resolved ALMA [CII] observations of the bright (flux density S=400 mJy at 350 microns), gravitationally lensed, starburst galaxy PLCK G045.1+61.1 at z=3.427, t…
FIR Spectroscopy of the Galactic Center: Hot and Warm Molecular Gas
J. R. Goicoechea, M. Etxaluze, J. Cernicharo +2
The angular resolution (~10") achieved by the Herschel Space Observatory ~3.5m telescope at FIR wavelengths allowed us to roughly separate the emission toward the inner parsec of t…
Spatial distribution of FIR rotationally excited CH+ and OH emission lines in the Orion Bar PDR
A. Parikka, E. Habart, J. Bernard-Salas +7
The abundance of CH+ and OH and excitation are predicted to be enhanced by the presence of vibrationally excited H2 or hot gas (~500-1000 K) in PDRs with high incident FUV radiatio…
