From large to small scales: The physical state of clouds from GMCs to clumps
Peter Barnes U Florida, Gainesville, US | |
| New results from two large-scale, unbiased, multi-species surveys of molecular clouds in the Galactic Plane (CHaMP, covering L=280 to 300, and ThrUMMS, covering L=300 to 360) are presented. These sensitive, wide-field maps of CO, CN, HCO+, HCN, N2H+, their isotopologues, and several other species, made with the Mopra telescope, yield distributions of column density, excitation, chemistry, and turbulence on all scales spanning GMCs (~100 pc) to clumps (~1 pc), and how these distributions relate to any embedded stellar populations and other environmental factors. The data will provide a number of constraints to theoretical models of cloud and star formation, PDRs, outflows, chemistry, dynamics, Galactic structure, and several other topics. | |
