DS2-T1 Final DeliverableDS2-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 SPDO’s Science Reference Mission and similar exercise by E-ELT

The FutureThe 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

21 cm simulated maps:exemples of recent results

Mellema et al. (2006)Valdés et al. (2006)

Beam=3.0 arcmin Bandwidth=0.13 MHz

20 Mpc/h

z=9.9

z=9.26

z=10.6 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)
