Spatial distribution of FIR rotationally excited CH(+) and OH emission lines in the Orion Bar PDR⋆

CONTEXT: The methylidyne cation (CH(+)) and hydroxyl (OH) are key molecules in the warm interstellar chemistry, but their formation and excitation mechanisms are not well understood. Their abundance and excitation are predicted to be enhanced by the presence of vibrationally excited H(2) or hot gas...
