THOR - The HI, OH, Recombination Line Survey of the Milky Way - The pilot study: HI observations of the giant molecular cloud W43
S. Bihr, H. Beuther, J. Ott +30
To study the atomic, molecular and ionized emission of Giant Molecular Clouds (GMCs), we have initiated a Large Program with the VLA: 'THOR - The HI, OH, Recombination Line survey…
The onset of high-mass star formation in the direct vicinity of the galactic mini-starburst W43
H. Beuther, J. Tackenberg, H. Linz +10
Context: The earliest stages of high-mass star formation are still poorly characterized. It is also unknown whether the initial conditions vary with environment. Aims: We want to i…
Large-scale Map of Millimeter-wavelength Hydrogen Radio Recombination Lines around a Young Massive Star Cluster
Q. Nguyen-Luong, L. D. Anderson, L. D. +19
We report the first map of large-scale (10 pc in length) emission of millimeter-wavelength hydrogen recombination lines (mm-RRLs) toward the giant H II region around the W43-Main y…
Low-velocity shocks traced by extended SiO emission along the W43 ridges: witnessing the formation of young massive clusters
Q. Nguyen Luong, F. Motte, P. Carlhoff +19
The formation of high-mass stars is tightly linked to that of their parental clouds. We here focus on the high-density parts of W43, a molecular cloud undergoing an efficient event…
Large scale IRAM 30m CO-observations in the giant molecular cloud complex W43
P. Carlhoff, Q. Nguyen Luong, P. Schilke +11
We aim to give a full description of the distribution and location of dense molecular clouds in the giant molecular cloud complex W43. It has previously been identified as one of t…
W43: the closest molecular complex of the Galactic Bar?
Q. Nguyen Luong, F. Motte, F. Schuller +9
We used a large database extracted from Galaxy-wide surveys of H {\scriptsize I}, CO 1-0, $8 \micron$ and $870 \micron$ continuum to trace diffuse atomic gas, low- to medium…
The formation of the W43 complex: constraining its atomic-to-molecular transition and searching for colliding clouds
F. Motte, Q. Nguyen Luong, N. Schneider +10
Numerical simulations have explored the possibility to form molecular clouds through either a quasi-static, self-gravitating mechanism or the collision of gas streams or lower-dens…
