the next decade?the next decade?

ALMA 2012?SKA 2020?

Maintaining the vitality of the astronomical community till SKA

What’s coming now in the SouthWhat’s coming now in the South

Atacama Plateau of Chile– 4m NANTEN2– 12m APEX– 12m ASTE– Plus, of course, ALMA

Antarctica– 1.7m AST/RO– 10m South Pole Telescope– 0.5m HEAT (THz frequencies)

What role for Australia’s facilities?What role for Australia’s facilities?

They’re here now!– only southern interferometer for > 5 years

7+12mm unchallenged, 3mm largely so.Broad Band, Fast Mapping.

Complementarity to the Chilean / Antarctic facilities?
