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…
Far-infrared observations of a massive cluster forming in the Monoceros R2 filament hub
T. S. M. Rayner, M. J. Griffin, N. Schneider +29
We present far-infrared observations of Monoceros R2 (a giant molecular cloud at approximately 830 pc distance, containing several sites of active star formation), as observed at 7…
Probing the baryon cycle of galaxies with SPICA mid- and far-infrared observations
F. F. S. van der Tak, S. C. Madden, P. Roelfsema +29
The SPICA mid and far-infrared telescope will address fundamental issues in our understanding of star formation and ISM physics in galaxies. A particular hallmark of SPICA is the o…
Galaxy evolution studies with the SPace IR telescope for Cosmology and Astrophysics (SPICA): the power of IR spectroscopy
L. Spinoglio, A. Alonso-Herrero, L. Armus +65
IR spectroscopy in the range 12-230 micron with the SPace IR telescope for Cosmology and Astrophysics (SPICA) will reveal the physical processes that govern the formation and evolu…
SPICA and the Chemical Evolution of Galaxies: The Rise of Metals and Dust
J. A. Fernández-Ontiveros, L. Armus, M. Baes +33
The physical processes driving the chemical evolution of galaxies in the last cannot be understood without directly probing the dust-obscured phase of star-for…
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 ALMA view of UV irradiated cloud edges: unexpected structures and processes
Javier R. Goicoechea, S. Cuadrado, J. Pety +8
Far-UV photons (E<13.6 eV) from hot massive stars regulate, or at least influence, the heating, ionization, and chemistry of most of the neutral interstellar medium. Investigating…
Multi-temperature mapping of dust structures throughout the Galactic Plane using the PPMAP tool with Herschel Hi-GAL data
K. A. Marsh, A. P. Whitworth, O. Lomax +13
We describe new Hi-GAL based maps of the entire Galactic Plane, obtained using continuum data in the wavelength range 70-500 m. These maps are derived with the PPMAP procedure,…
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…
First detection of THz water maser in NGC7538-IRS1 with SOFIA and new 22 GHz e-MERLIN maps
F. Herpin, A. Baudry, A. M. S. Richards +7
The formation of massive stars is still not well understood. Accumulating a large amount of mass infalling within a single entity in spite of radiation pressure is possible if, amo…
Spatially resolved images of reactive ions in the Orion Bar
Javier R. Goicoechea, S. Cuadrado, J. Pety +6
We report high angular resolution (4.9" x 3.0") images of reactive ions SH+, HOC+, and SO+ toward the Orion Bar photodissociation region (PDR). We used ALMA-ACA to map several rota…
Planet Formation in AB Aurigae: Imaging of the inner gaseous Spirals observed inside the Dust Cavity
Ya-Wen Tang, Stephane Guilloteau, Anne Dutrey +13
We report the results of ALMA observations of a protoplanetary disk surrounding the Herbig Ae star AB Aurigae. We obtained high-resolution (0.1"; 14 au) images in CO (J=2-1)…
State-to-state chemistry and rotational excitation of CH in photon-dominated regions
A. Faure, P. Halvick, T. Stoecklin +9
We present a detailed theoretical study of the rotational excitation of CH due to reactive and nonreactive collisions involving C, H, CH, H and free electrons.…
On the reservoir of sulphur in dark clouds : chemistry and elemental abundance reconciled
Thomas H. G. Vidal, Jean-Christophe Loison, Adam Yassin Jaziri +3
Sulphur-bearing species are often used to probe the physical structure of star forming regions of the interstellar medium, but the chemistry of sulphur in these regions is still po…
The earliest phases of high-mass star formation, as seen in NGC 6334 by \emph{Herschel}
J. Tigé, F. Motte, D. Russeil +33
To constrain models of high-mass star formation, the Herschel/HOBYS KP aims at discovering massive dense cores (MDCs) able to host the high-mass analogs of low-mass prestellar core…
ALMA survey of massive cluster progenitors from ATLASGAL. Limited fragmentation at the early evolutionary stage of massive clumps
T. Csengeri, S. Bontemps, F. Wyrowski +18
The early evolution of massive cluster progenitors is poorly understood. We investigate the fragmentation properties from 0.3 pc to 0.06 pc scales of a homogenous sample of infrare…
Herschel observations of the Galactic HII region RCW 79
Hong-Li Liu, Miguel Figueira, Annie Zavagno +12
Triggered star formation around HII regions could be an important process. The Galactic HII region RCW 79 is a prototypical object for triggered high-mass star formation. We take a…
A study of singly deuterated cyclopropenylidene c-C3HD in protostar IRAS 16293-2422
L. Majumdar, P. Gratier, I. Andron +2
Cyclic-C3HD (c-C3HD) is a singly deuterated isotopologue of c-C3H2, which is one of the most abundant and widespread molecules in our Galaxy. We observed IRAS 16293-2422 in the 3 m…
