Molecules in the Circumnuclear Disk of the Galactic Center
Nanase Harada, Denise Riquelme, Serena Viti +4
Within a few parsecs around the central Black Hole Sgr A*, chemistry in the dense molecular cloud material of the circumnuclear disk (CND) can be affected by many energetic phenome…
The CHESS survey of the L1157-B1 bow-shock: high and low excitation water vapor
G. Busquet, B. Lefloch, M. Benedettini +9
Molecular outflows powered by young protostars strongly affect the kinematics and chemistry of the natal molecular cloud through strong shocks resulting in substantial modification…
A combined IRAM and Herschel/HIFI study of cyano(di)acetylene in Orion KL: tentative detection of DC3N
G. B. Esplugues, J. Cernicharo, S. Viti +8
We present a study of cyanoacetylene (HC3N) and cyanodiacetylene (HC5N) in Orion KL, through observations from two line surveys performed with the IRAM 30m telescope and the HIFI i…
The B1 shock in the L1157 outflow as seen at high spatial resolution
M. Benedettini, S. Viti, C. Codella +7
We present high spatial resolution (750 AU at 250 pc) maps of the B1 shock in the blue lobe of the L1157 outflow in four lines: CS (3-2), CH3OH (3_K-2_K), HC3N (16-15) and p-H2CO (…
Broad N2H+ emission towards the protostellar shock L1157-B1
C. Codella, S. Viti, C. Ceccarelli +8
We present the first detection of N2H+ towards a low-mass protostellar outflow, namely the L1157-B1 shock, at about 0.1 pc from the protostellar cocoon. The detection was obtained…
A radical route to interstellar propylene formation
J. M. C. Rawlings, D. A. Williams, S. Viti +1
Complex organic molecules, such as propylene (CH3CHCH2), are detected in molecular clouds (such as TMC1) with high fractional abundances (~2.10^{-9}, relative to hydrogen) that can…
74 MHz Nonthermal Emission from Molecular Clouds: Evidence for a Cosmic Ray Dominated Region at the Galactic Center
F. Yusef-Zadeh, M. Wardle, D. Lis +5
We present 74 MHz radio continuum observations of the Galactic center region. These measurements show nonthermal radio emission arising from molecular clouds that is unaffected by…
Spatial distribution of small hydrocarbons in the neighborhood of the Ultra Compact HII region Monoceros R2
P. Pilleri, S. Treviño-Morales, A. Fuente +14
We study the chemistry of small hydrocarbons in the photon-dominated regions (PDRs) associated with the ultra-compact HII region Mon R2. Our goal is to determine the variations of…
Widespread Methanol Emission from the Galactic Center
F. Yusef-Zadeh, W. Cotton, S. Viti +2
We report the discovery of a widespread population of collisionally excited methanol J = 4_{-1} to 3$_0 E sources at 36.2 GHz from the inner 66'x18' (160x43 pc) of the Galactic cen…
Episodic Explosions in Interstellar Ices
J. M. C. Rawlings, D. A. Williams, S. Viti +1
We present a model for the formation of large organic molecules in dark clouds. The molecules are produced in the high density gas-phase that exists immediately after ice mantles a…
