Localising the VHE gamma-ray source at the Galactic Centre

The HESS Collaboration, F. Acero

The inner 10 pc of our galaxy contains many counterpart candidates of the very high energy (VHE; > 100 GeV) gamma-ray point source HESS J1745-290. Within the point spread function…

Intermittency of interstellar turbulence: extreme velocity-shears and CO emission on milliparsec scale

E. Falgarone, J. Pety, P. Hily-Blant

The condensation of diffuse gas into molecular clouds occurs at a rate driven largely by turbulent dissipation. This process still has to be caught in action and characterized. A m…

Spitzer spectral line mapping of protostellar outflows: I. Basic data and outflow energetics

David A. Neufeld, Brunella Nisini, Teresa Giannini +7

We report the results of spectroscopic mapping observations carried out toward protostellar outflows in the BHR71, L1157, L1448, NGC 2071, and VLA 1623 molecular regions using the…

The Foggy Disks Surrounding Herbig Ae Stars: a Theoretical Study of the H2O Line Spectra

J. Cernicharo, C. Ceccarelli, F. Menard +2

Water is a key species in many astrophysical environments, but it is particularly important in proto-planetary disks. So far,observations of water in these objects have been scarce…

On the robustness of the ammonia thermometer

Sebastien Maret, Alexandre Faure, Emanuele Scifoni +1

Ammonia inversion lines are often used as probes of the physical conditions in the dense ISM. The excitation temperature between the first two para metastable (rotational) levels i…

The environment of formation as a second parameter for globular cluster classification

Didier Fraix-Burnet, Emmanuel Davoust, Corinne Charbonnel

We perform an evolutionary multivariate analysis of a sample of 54 Galactic globular clusters with high-quality colour-magnitude diagrams and well-determined ages. The four paramet…

Spectrum and variability of the Galactic Center VHE gamma-ray source HESS J1745-290

H. E. S. S. collaboration, :, F. Aharonian

A detailed study of the spectrum and variability of the source HESS J1745-290 in the Galactic Center (GC) region using new data from the H.E.S.S. array of Cherenkov telescopes is p…

Intermittency of interstellar turbulence: Parsec-scale coherent structure of intense velocity-shear

Pierre Hily-Blant, Edith Falgarone

Guided by the duality of turbulence (random versus coherent we seek coherent structures in the turbulent velocity field of molecular clouds, anticipating their importance in cloud…

CO emission and variable CH and CH+ absorption towards HD34078: evidence for a nascent bow shock ?

P. Boisse, E. Rollinde, P. Hily-Blant +7

The runaway star HD34078, initially selected to investigate small scale structure in a foreground diffuse cloud has been shown to be surrounded by highly excited H2. We first searc…

Six more quasars at redshift 6 discovered by the Canada-France High-z Quasar Survey

C. J. Willott, P. Delorme, C. Reyle +9

We present imaging and spectroscopic observations for six quasars at z>5.9 discovered by the Canada-France High-z Quasar Survey (CFHQS). The CFHQS contains sub-surveys with a range…
