Formation of Structure in Molecular Clouds: A Case Study
F. Heitsch, A. Burkert, L. Hartmann +2
Molecular clouds (MCs) are highly structured and ``turbulent''. Colliding gas streams of atomic hydrogen have been suggested as a possible source of MCs, imprinting the filamentary…
Structure Generation by Irradiation: What can GLIMPSE teach us about the ISM structure?
F. Heitsch, B. Whitney, R. Indebetouw +4
Diffuse emission in the mid-infrared shows a wealth of structure, that lends itself to high-resolution structure analysis of the interstellar gas. A large part of the emission come…
Physical Properties of Complex C Halo Clouds
W. -H. Hsu, M. E. Putman, F. Heitsch +3
Observations from the Galactic Arecibo L-Band Feed Array HI (GALFA-HI) Survey of the tail of Complex C are presented and the halo clouds associated with this complex cataloged. The…
The Birth of Molecular Clouds: Formation of Atomic Precursors in Colliding Flows
F. Heitsch, A. D. Slyz, J. E. G. Devriendt +2
Molecular Cloud Complexes (MCCs) are highly structured and ``turbulent''. Observational evidence suggests that MCCs are dynamically dominated systems, rather than quasi-equilibrium…
Initial Conditions for Star Formation: A Physical Description of the Filamentary ISM
A. Hacar, S Clark, F. Heitsch +4
The interstellar medium contains filamentary structure over a wide range of scales. Understanding the role of this structure, both as a conduit of gas across the scales and a diagn…
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…
