  1. VO Theory Use Cases –Intermediate Scale David De Young Project Scientist US NVO IVOA Theory Interest Group S. Lorenzo del Escorial - 10/05

  2. VO Theory Use Cases –Intermediate Scale • Two Principal Areas Explored to Date • N Body Simulations of Globular Cluster Evolution • 2 D and 3 D MHD Simulations of Collimated Outflows from AGN

  3. N Body Simulations of Globular Cluster Evolution • P. Hut, P. Teuben et al. • Follows Dynamical and Chemical Evolution of 100,000 Individual Stars • Tracks Individual Orbits, Binary Capture, etc.

  4. N Body Simulations of Globular Cluster Evolution • Some Astrophysics Addressed: • Overall Cluster Evolution • Core Collapse • Binary Fraction; X-Ray Luminosity • Evolution of HR Diagram • Late Stages of Stellar Evolution and Mass Loss • Allows Direct Comparison with Observations

  5. N Body Simulations of Globular Cluster Evolution

  6. N Body Simulations of Globular Cluster Evolution

  7. N Body Simulations of Globular Cluster Evolution

  8. N Body Simulations of Globular Cluster Evolution • Data Requirements: • Does Not Use Arrays for Most Data • Follows Time Intervals of Individual Orbits • Stores Orbital Data with Differing Timelines • Requires Fly Through Capability • Uses AMNH Rose Planetarium • Size of Data Sets: ~ TB

  9. N Body Simulations of Globular Cluster Evolution • Requires Definition of Theory MetaData Standards Before Further Progress Can Be Made

  10. MHD Simulations of Collimated Outflows from AGN • T. Jones, D. De Young, I. Tregillis, S. O’Neal et al. • Self Consistent MHD Simulations of Large Scale Outflows to ~ 100 kpc • Follows Evolution of Relativistic Particle Population Including Shock Acceleration

  11. MHD Simulations of Collimated Outflows from AGN • Some Astrophysics Addressed • Global Evolution of Large Scale Jets • Role of Interaction with Ambient Medium – Entrainment and Jet Deceleration • Evolution of Magnetic Amplification • Evolution of Particle Spectrum • Distribution of Synchrotron Radiation as a Function of Space and Time

  12. MHD Simulations of Collimated Outflows from AGN Radio Electrons VLA

  13. MHD Simulations of Collimated Outflows from AGN IC-CMB Chandra SSC

  14. MHD Simulations of Collimated Outflows from AGN

  15. MHD Simulations of Collimated Outflows from AGN • Code is Fully Parallel • Now Running at San Diego Supercomputer Ctr. • Data Format Highly Specialized, Non Std. • Subsequent Complex Post Processing Required • Size of Raw Data Sets: Up to Tb per Run

  16. MHD Simulations of Collimated Outflows from AGN • Requires Definition of Theory MetaData Standards Before Further Progress Can Be Made
