Influence of galactic arm scale dynamics on the molecular composition of the cold and dense ISM I. Observed abundance gradients in dense clouds
M. Ruaud, V. Wakelam, P. Gratier +1
Aims. We study the effect of large scale dynamics on the molecular composition of the dense interstellar medium during the transition between diffuse to dense clouds. Methods. We f…
First detection of interstellar S2H
Asunción Fuente, Javier R. Goicoechea, Jerome Pety +11
We present the first detection of gas phase S2H in the Horsehead, a moderately UV-irradiated nebula. This confirms the presence of doubly sulfuretted species in the interstellar me…
Clustering the Orion B giant molecular cloud based on its molecular emission
Emeric Bron, Chloé Daudon, Jérôme Pety +12
Previous attempts at segmenting molecular line maps of molecular clouds have focused on using position-position-velocity data cubes of a single line to separate the spatial compone…
Methyl isocyanate CH3NCO: An important missing organic in current astrochemical networks
Liton Majumdar, Jean-Christophe Loison, Maxime Ruaud +3
Methyl isocyanate (CH3NCO) is one of the important complex organic molecules detected on the comet 67P/Churyumov-Gerasimenko by Rosetta's Philae lander. It was also detected in hot…
The interstellar chemistry of C3H and C3H2 isomers
Jean-Christophe Loison, Marcelino Agundez, Valentine Wakelam +6
We report the detection of linear and cyclic isomers of C3H and C3H2 towards various starless cores and review the corresponding chemical pathways involving neutral (C3Hx with x=1,…
A new study of the chemical structure of the Horsehead nebula: the influence of grain-surface chemistry
Romane Le Gal, Eric Herbst, Gwenaelle Dufour +4
A wide variety of molecules have recently been detected in the Horsehead nebula photodissociation region (PDR) suggesting that: (i) gas-phase and grain chemistries should both cont…
