The anatomy of the Orion B Giant Molecular Cloud: A local template for studies of nearby galaxies
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-30m to spatiallyExpand
The ionization fraction gradient across the Horsehead edge: an archetype for molecular clouds
Context. The ionization fraction (i.e., the electron abundance) plays a key role in the chemistry and dynamics of molecular clouds. Aims. We study the H 13 CO + ,D CO + and HOC + line emissionExpand
Low sulfur depletion in the Horsehead PDR
Aims.We present 3.65'' × 3.34'' angular-resolution IRAM Plateau de Bure Interferometer (PdBI) observations of the CS J = 2-1 line toward the Horsehead Photodissociation Region (PDR), complementedExpand
Herschel Survey of Galactic OH+, H2O+, and H3O+: Probing the Molecular Hydrogen Fraction and Cosmic-Ray Ionization Rate
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, and continuesExpand
THE CHEMISTRY OF INTERSTELLAR OH+, H2O+, AND H3O+: INFERRING THE COSMIC-RAY IONIZATION RATES FROM OBSERVATIONS OF MOLECULAR IONS
We model the production of OH+, H2O+, and H3O+ in interstellar clouds, using a steady-state photodissociation region code that treats the freezeout of gas species, grain surface chemistry, andExpand
The chemistry and spatial distribution of small hydrocarbons in UV-irradiated molecular clouds: the Orion Bar PDR
This work has been partially funded by MINECO grants (CSD2009-00038, AYA2009-07304, and AYA2012-32032). S.C. acknowledges support from FPI-INTA grant. P.P. acknowledges financial support from theExpand
Formation of simple organic molecules in inner T Tauri disks
Aims. We present time dependent chemical models for a dense and warm O-rich gas exposed to a strong, far ultraviolet (FUV) field aimed at exploring the formation of simple organic molecules in theExpand
Herschel Measurements of Molecular Oxygen in Orion
We report observations of three rotational transitions of molecular oxygen (O2) in emission from the H2 Peak 1 position of vibrationally excited molecular hydrogen in Orion. We observed the 487 GHz,Expand
The IRAM-30 m line survey of the Horsehead PDR - II. First detection of the l-C3H+ hydrocarbon cation
Context. Pure gas-phase chemistry models do not succeed in reproducing the measured abundances of small hydrocarbons in the interstellar medium. Information on key gas-phase progenitors of theseExpand
VELOCITY-RESOLVED [C ii] EMISSION AND [C ii]/FIR MAPPING ALONG ORION WITH HERSCHEL.
TLDR
It is concluded that the [C ii] emitting column relative to the total dust column along each line of sight is responsible for the observed L[C ii?]/LFIR variations through the cloud. Expand
