SKADS Virtual Telescope Four Years in the
Life Analysis

• Stage A 2011, 120 6-m (0.3 SKA) Telescopes
• Stage B 20122013, 500 6-m (1.2 SKA)
  Telescopes
• Stage C 2014, 2000 6-m Telescopes 20k m2 AA
  (7 SKA)
• Why? Practice for final SKADS DS2 deliverable
  high- frequency capable to illustrate all SKA
  science
• Final deadline was Sep 21, 2007
• 30 proposals
• We are now going to schedule the SVT (at first
  with fixed configurations)
• Excludes EOR array science case (example of
  generic problem of avoiding separate projects)

Example output of SVT analysis

• Stage A (2011 0.3 SKA with 40-arcsec
  resolution)
• 1000 extragalactic deg2 1.15-1.4 GHz gtgt100k HI
  galaxies to z0.2
• RM grid 20-arcmin separation
• Confusion limited in continuum
• 50 extragalactic (FMOS/VISTA) deg2
  0.7-1.2 GHz stacked HI to z1
• 20,000 deg2 3GHz (300 µJy) survey spectral
  indices (curvatures with LOFAR) for all FIRST
  sources repeat visits to do slow transients
  (including orphan GRBs ESEs!)
• Learn (analysing compact baselines in the
  bunker!) how to piggyback pulsar/RRAT search
  experiments with other science, lunar Cerenkov,
  cosmic rays etc
• high-freq experiments e.g. pointed
  SZ on 100 high-z Planck clusters
• VERY FAR FROM A SINGLE-ISSUE TELESCOPE!

Example output of SVT analysis

• Stage B (20122013 1.2SKA with 8-arcsec
  resolution)
• 20,000 extragalactic deg2 1.15-1.4 GHz gt1m HI
  galaxies to z0.2
• RM grid all sky
• Continuum survey to 100 microJy
• Piggyback slow transient work
• 50 extragalactic (FMOS/VISTA) deg2
  0.7-1.2 GHz stacked HI to z1
• 1,000 extragalactic deg2 3GHz (50 µJy) survey
  spectral indices (curvatures with LOFAR) for
  SVT population piggyback slow transients
  (faint ESEs!)
• Galactic Plane survey HI, 3GHz important for
  Faraday tomography
• Pulsar/RRAT searches (piggybacking?) 100s of
  RRATs, maybe exotics
• high-freq experiments e.g. (with
  VLBI) Cradle of Life, high-z low-J CO
