  1. 25. Gas Flows in Galaxy Clusters
    Dr Brian McNamara (University of Waterloo)
    11/08/2014, 14:00
    Program
    Galaxies and clusters are embedded in gaseous hot atmospheres that serve as repositories of unused fuel for galaxy formation, ejecta from evolved stars, and mechanical energy released by supermassive black holes. The hot gas located within the central galaxy is expected to cool and fuel star formation. Yet most giant elliptical galaxies are "red and dead."  Instead, cooling is suppressed by...

  2. 15. Witnessing the ongoing growth of nearby clusters of galaxies
    Dr Aurora Simionescu (ISAS/JAXA)
    11/08/2014, 14:25
    Program
    Over the past several years, the comparatively low background of the Suzaku satellite has enabled measurements of the thermodynamic properties of the faint cluster outskirts, opening a new window for the exploration of the ongoing virialization and equilibration processes that occur as part of large-scale structure formation. This has been complemented by several subsequent studies with...

  3. 23. New observational constraints on microphysical properties of the intracluster plasma
    Dr Maxim Markevitch (NASA/GSFC)
    11/08/2014, 14:50
    Program
    I will present new observational constraints on large-scale thermal conductivity of the ICM, based on radial profiles for relaxed clusters. Constraints on electron-proton equilibration timescale from new analysis of the shock front in A520 and reanalysis of the shock in Bullet will also be presented.

  4. 4. Stratified Turbulence, Heating, Cooling and Diffusion in Galaxy Clusters
    Prof. Alexander Schekochihin (University of Oxford)
    11/08/2014, 16:00
    Program
    I will discuss what can be inferred about the structure of stratified turbulence in galaxy clusters from basic assumptions such as a generalised principle of critical balance [3,4]. I will then discuss how the conclusions from this exercise lead to a useful prescription for deducing velocity spectra in the ICM from the density fluctuation spectra [2] (measurable by existing X-ray...

  5. 11. High-order Numerical Methods for Plasma Simulations on Large-scale High-Performance Computing Architectures
    Dr Dongwook Lee (The University of Chicago)
    11/08/2014, 16:25
    Program
    Modeling diverse physical processes using mathematical algorithms has become a successful tool in modern science and engineering. The underlying mathematical models are carefully designed to perform large-scale computer simulations that involve disparate scales of space and time. Such complexities often arise when incorporating various multi-physics components that can be represented by...
