    Nonlinear evolution of bistable interstellar medium is investigated using two-dimensional simulations with a realistic cooling rate, heat conduction, and physical viscosity. The calculation is performed in periodic boundary conditions without any external forcing. As the initial condition, spatially uniform unstable gas under thermal equilibrium is considered. At the initial stage, the...

    Recent observational results have shown that local interstellar filaments follow a thickness distribution which is surprisingly narrowly peaked at 0.1 pc for a wide range of column densities. This fact is pertinent to the study of interstellar gases as a fingerprint of the physical mechanisms acting on that scale. But what can create structure of a characteristic size when both gravity and...

  4. 94. Anomalous extinction: The degeneracy between dust composition and geometry
    Peter Scicluna (ESO)

    contributed talk
    The spatial distribution of dust has significant influence on the observed extinction curve. As a result, when observing anisotropic, clumpy or turbulent environments the aperture may contain a wealth of unresolved structure. Hence, observations only probe an effective optical depth and effective extinction curve. In order to elucidate and quantify the impact of unresolved structure we perform...

  5. 110. Latest GREAT results from SOFIA
    Hans Zinnecker (Deutsches SOFIA Institut)

    contributed talk
    I will present a short summary of the status of SOFIA, the Stratospheric Observatory for Infrared Astronomy. SOFIA has been deployed to the Southern Hemisphere in July 2013 and completed 9 successful flights out of Christchurch, New Zealand. Some amazing results from from these FIR observations with GREAT are emerging, including detection of the 2.5 THz OH and 2.7 THz HD ground state...
