DS2-T1 Final Deliverable

• Year in Life
• Will build on SKADS Virtual Telescope (SVT)
  Exercise, but now with sky simulation tools
  fullly in place
• What data simulation tools will be in place (see
  DS2-T2 talks)?
• Relation to SPDOs Science Reference Mission and
  similar exercise by E-ELT

The Future
Path2SKA Marie Curie ITN submitted Sep 2008. 30
early-stage researchers with a significant sky
simulation component. If funded will maintain
European lead in global sky simulation
effort. Whether, or not, funded, ESKAC will
continue to develop European SKA science
community. Will exploit modern simulations,
continue to utilize data constraints, and will
increase synergies with SKA pathfinders and
experiments at other wavebands.

Introduction

Box size is crucial Currently from 1 Mpc to
100 Mpc. - Small boxes statistics issues -
Large boxes bad resolution (use of a clumping
factor) ? faster reionization. In all
case Lyman-alpha flux not
simulated ! (assumed uniform)
