High-resolution mapping of the physical conditions in two nearby active galaxies based on 12CO(1-0), (2-1) and (3-2) lines
F. Boone, S. Garcia-Burillo, F. Combes +7
We present a detailed analysis of high resolution observations of the three lowest CO transitions in two nearby active galaxies, NGC4569 and NGC4826. The CO(1-0) and (2-1) lines we…
Tracing gas accretion in the Galactic center using isotopic ratios
D. Riquelme, M. A. Amo-Baladron, J. Martin-Pintado +3
Ams: We study the 12C/13C isotopic ratio in the disk of the central molecular zone and in the halo to trace gas accretion toward the Galactic center region in the Milky Way. Method…
Variations in H2O+/H2O ratios toward massive star-forming regions
F. Wyrowski, F. van der Tak, F. Herpin +63
Early results from the Herschel Space Observatory revealed the water cation H2O+ to be an abundant ingredient of the interstellar medium. Here we present new observations of the H2…
Nitrogen hydrides in interstellar gas: Herschel/HIFI observations towards G10.6-0.4 (W31C)
C. M. Persson, J. H. Black, J. Cernicharo +49
The HIFI instrument on board the Herschel Space Observatory has been used to observe interstellar nitrogen hydrides along the sight-line towards G10.6-0.4 in order to improve our u…
A HIFI preview of warm molecular gas around chi Cyg : first detection of H2O emission toward an S-type AGB star
K. Justtanont, L. Decin, F. L. Schoier +24
A set of new, sensitive, and spectrally resolved, sub-millimeter line observations are used to probe the warm circumstellar gas around the S-type AGB star chi Cyg. The observed lin…
G30.79~FIR~10: A gravitationally bound infalling high-Mass star forming clump
P. C. Cortes, R. Parra, J. R. Cortes +1
Infalling motions were detected and modeled toward this source. A mean infall velocity of 0.5 km/s with an infall mass rate of 5x10^-3 Solar masses per year was obtained. Also, a p…
