21/10/2013, 09:00PosterThe Lupus I cloud complex is located in the collision zone between two expanding super-bubbles that are driven by the massive stars in two sub-groups of the ScoCen OB association. With a distance of just 150 pc, it represents the nearest example where we can study how such a collision process forms new dense clouds in the ISM. With multi-wavelength data available, we are able to condcut a...Go to contribution page

Andy Pon (University of Leeds)21/10/2013, 09:00PosterMolecular clouds exhibit large linewidths, which are usually interpreted as being due to supersonic turbulence. This turbulence plays a key role in many theories of star formation, as it is believed to help support and fragment molecular clouds. Current numerical MHD simulations show that the turbulent energy of a molecular cloud dissipates on the order of a crossing time, but do not...Go to contribution page

Robertas Aluzas (School of Physics and Astronomy, University of Leeds)21/10/2013, 09:00PosterThe interstellar medium (ISM) is highly structured and inhomogeneous. Density enhancements (clouds) that occupy a small volume fraction can dominate the mass fraction. The interaction between clouds and flows is a key process affecting the behaviour and evolution of the ISM, with implications for star formation and galaxy evolution. For instance, dense clouds may be destroyed by a flow, while...Go to contribution page

21/10/2013, 09:00PosterWe numerically study the volume density probability density function (n-PDF) and the column density probability density function (\sigma-PDF) resulting from thermally bistable turbulent flows with and without self-gravity. For this aim we analyze three- dimensional hydrodynamic models in periodic boxes of 100pc by side with forced turbulence at large scales and different Mach numbers (M). At...Go to contribution page

Ji-hyun Kang (Korea Astronomy and Space Science Institute)21/10/2013, 09:00PosterTurbulence study of the neutral hydrogen gas associated with supernova remnants (SNRs) has not been done so far, in spite of the fact that many HI surveys have been used to characterize the turbulent interstellar medium. This is mainly because the shocked HI emission of SNRs is difficult to be distinguished from the ambient HI emission in the Galactic Plane. We notice that some expanding HI...Go to contribution page

Cinthya Herrera (NAOJ)21/10/2013, 09:00PosterThe Antennae are a spectacular example of a burst of star formation triggered by the encounter of two galaxies. They are an ideal source to understand how the dynamics of galaxies in mergers trigger the star formation. In the Antennae, most of the newly formed stars are observed in massive clusters (up to 10^7 Msun), dubbed super star clusters, located in the region where the two galaxies...Go to contribution page

Lukas Konstandin (Institut für Theoretische Astrophysik, Heidelberg)21/10/2013, 09:00PosterObservations reveal that supersonic turbulence is prevalent in star forming clouds. The density and velocity field within these clouds indicate complex, chaotic, and filamentary structures, where turbulent motions interact with shocks. Therefore, understanding the properties of turbulence is a prerequisite for developing a comprehensive theory of star formation in the ISM. We study a set of...Go to contribution page
