We also request GBT-ARGUS time to map 13CO(1-0) and C18O(1-0) at high angular and velocity resolution to obtain the best maps of molecular gas kinematics to compare to those of and further test models of IRDC dynamics and formation. These will be tested against upGREAT observations to deduce the processes that initiate star cluster formation. For example, simulations of dense gas formation via either decaying turbulence or triggering by cloud-cloud collisions make specific distinguishing predictions for spatial and kinematic structures. Different theoretical models of IRDC formation are expected to have different signatures of kinematics. Thus it provides crucial information on the kinematics of the gas that is becoming molecular and joining the IRDC. probes the photodissociation region around the IRDC. We propose to utilize the efficient OTF mapping capabilities of upGREAT to map and emission in a sample of 3 IRDCs that have been extremely well studied over the last decade with numerous facilities, including Spitzer, IRAM 30m, IRAM PdBI, Herschel, Chandra & ALMA. Thus it is important to understand the kinematics, dynamics & formation environments of IRDCs. Infrared Dark Clouds (IRDCs) are now recognized as the likely precursors of star clusters. Thus, the processes that may initiate star cluster formation are of fundamental importance throughout astrophysics, from the evolution of stellar populations in galaxies to the formation of planets in protoplanetary disks in these environments.

Principal Investigator: Jonathan Tan (University of Virginia) More information on the Green Bank Observatory website. Up to 5% of the total open-skies time on the GBT will be reserved for proposals received via this call, and up to 3% of the total US GO time on SOFIA will be reserved for proposals received by the GBO. This agreement allows users to apply for time with the Green Bank Telescope via the SOFIA proposal process or for time with SOFIA via the Green Bank Telescope (GBT) proposal process. The SMO has made an agreement for joint proposals with the Green Bank Observatory (GBO).
